What’s The Best Antenna For Your Helium Hotspot?

Here is a step by step method for understanding how to choose the best antenna for your hotspot placement. Each placement demands a well matched antenna in order to provide value to the Helium Network and consequently earn the most HNT possible for that location. Do NOT, by the way, try to get the giant antenna in the picture below. While it looks huge and cool and rad, it is the wrong antenna to use for these deployments. I spent a fair amount of blood and treasure to learn that lesson. You don’t need to.

First: Hotspot placement optimization is FAR more important than what antenna you use, more on that here.

Second, for those of you who just want AN ANSWER: Simple: Pick up one of these if you’re on a budget (use code GRISTLEKING to knock off another 5%), get this if have plenty to spend or choose from the McGill selection. They’ll all work well.

Put it outdoors at least 10′ above all the buildings around you. Run 40′ or less of LMR400 cable to it from your hotspot. If you have to go more than 40′, use LMR600 if you’re feeling extravagant. That’ll probably get you 80% of the results you could get with far more effort and expertise.

Wait, you want to actually learn and match your antenna to your situation so you get the maximum rewards possible?

Ok, let’s start with broad strokes: The antenna you choose for your hotspot placement should match your topography, your elevation, and your lines of sight.

Let’s start with topography. Topography refers to the buildings, earth, and water that surround, channel, and block your radio signals (propagation.) The topic of radio propagation involves a tremendously deep dive all the way down to the fundamentals of physics, but we’ll keep it pretty simple.

BLUF (Bottom Line Up Front) – The flatter your topography AND the more trees/vegetation you have blocking your Line of Sight to other hotspots, the higher gain antenna you can use, up to 9 dbi.

Remember, topography isn’t just hills and mountains, it includes buildings, trees, and other obstacles.

Ok, let’s get dirty! In general, earth in the form of mountains or hills will block radio signals. Even though a hotspot may seem very close to you, if there’s a hill between the two of you, you probably won’t witness each other.

You may check out your location on the Helium Explorer Coverage map and think you’re perfectly positioned in regards to nearby hotspots, like this:

Remember to check Google Earth!

See how that spot is tucked into a bunch of hills? Unless you put up an antenna that’ll stick over the top of the hills, you’re restricted to witnessing only other hotspots in your immediate area, and in this case, that area is small!

One of the best tools to use when assessing a new site is HeliumVision. Remember, location is FAR more important than antennas. If you’d like to learn more about HeliumVision (I use it in every one of my consults) I’ve built a Master Class on it, over here.

Ok, so that’s earth. Earth = No Radio Waves Getting Through.

What about buildings? How much will buildings block or reduce the power of radio propagation?

According to a study done in 2012 on a wide swath of building materials and focusing on the GSM 900 MHz band, a reinforced concrete wall that is 20cm / ~8″ thick will attenuate the signal by 27 dB. An interior plaster wall will reduce power by anywhere from .8 to 3 dB.

What does that mean? Disclaimer: RF geeks, I’ma get loose with terms here. Relax.

This reduction in power is called “attenuation.” In general with radio communications, you don’t want any attenuation. Attenuation can happen with earth, buildings, forests, and even window coatings. How much power will you lose? Let’s run some numbers.

American based hotspots start off by pushing out 27 dBm. European and other areas start WAY lower, at 14. Add the gain (dBi) from your antenna and subtract the losses from any connections to figure out your Effective Isotropic Radiated Power (EIRP).

That means a 6 dBi antenna will give you 33 dBm of EIRP with a US hotspot. 27dBm + 6dBi = 33dBm in the direction of antenna gain. Now you’ve got to calculate cable and connection loss.

As a rough rule of thumb, each connection (hotspot to antenna cable, antenna cable to antenna, or going through an enclosure wall using a connector) will drop your EIRP by .5 dB. Cable losses vary by cable, which is why most people use a “low loss” cable like LMR400. If you want to run your EIRP numbers, here’s how.

Ok, ok, ok, why does it matter whether or not you know your EIRP?

Let’s take a short detour into dBm and power. dBm is based on a logarithmic scale. For every increase of 3 dBm, there is twice as much power output. Every increase of 10 dBm has a tenfold increase in power. The difference between a 3 dBi antenna (what most hotspots ship with) and an aftermarket 9 dBi antenna is a factor of 4!

Of course, that 4x power comes at a cost; the beam is focused; more laser and less lightbulb. That means that unless you aim your antenna very carefully, you can blast all that power into places that have no hotspots.

Here is a great example demonstrating attenuation and topography. This hotspot is placed on the north side inside a building. It’s up high with a higher gain antenna, and in general, inaccurately aimed over most of the nearby hotspots.

Most of the witnesses it’s getting are further north. Some of the signals bounce off to the side, proving that “RF is weird.”

To the south, the signals are blocked or attenuated by interior and exterior walls, but apparently there is a small window or opening where those weakened signals are escaping, then going pretty far over the water. Pretty neat, right? I mean, not for the hotspot owner, but it’s a neat demonstration of the concept.

That image is also a great example of why you should never put a hotspot antenna inside; you are losing a ton of power before the radio waves ever get outside the building.

Water allows radio signals to travel much further than normal; look at any hotspot next to a body of water and you’ll see it will connect with other hotspots at much further ranges across the water than it will across land.

Let’s not get too into the weeds here. As I said at the beginning, the general rule for topography is this: The flatter your topography, the higher gain antenna you can use, up to 9 dBi for 95% of placements. Beyond 9 the pattern generally gets too precise to provide the Wide coverage (the W in WUPU) that we want.

Remember, topography includes not just hills, mountains, and water, but all the buildings, bridges, and other structures that might block your radio signal. Cities in general do not have a flat topography, even if they’re built on flat land. All those spiky buildings sticking out will gobble up your radio signals.

That brings us to ELEVATION. If you want to bend your mind a little bit, think about this: The higher your elevation, the flatter the relative topography is, and the LOWER dbi antenna you can use. Wait, what?

Remember, a high dbi antenna focuses the signal of your antenna. In an omni antenna (we’ll get to directional or sector antennas in a minute), that shape becomes a flatter and flatter plane. If that plane is super flat, it’ll fly right over the tops of all those hotspots you want to hit. Let’s go through 3 examples.

Now, those aren’t how it *actually* works. The gain patterns are nowhere near as different, and a high gain antenna will STILL hit the ground within 1,000′ of even a 100′ building. Still, you can see why in *most* cases, you want a low or medium gain antenna up high.

You can also run that idea backwards; if you’re in a really flat area where you don’t have a lot of obstacles, a high gain antenna might be your best bet. Still, most people don’t live in the desert, and the flattest state in America has a ton of trees on it. If that’s your scenario, get a high gain (6-9 dBi) antenna up over the tops of those trees for maximum coverage.

That brings us in a roundabout way to Lines of Sight. Remember that $39 paper I quoted earlier regarding how much RF energy a given building material would absorb? The general takeaway for us Helium Hotspot owners is this: Our antennas won’t blast through much more than 2 buildings.

That means if you’re INSIDE the building, you’ve burned most of the energy of the antenna just getting outside the walls. If it hits just one more “thing”, whether it’s a building, a tree, or a billboard, that’s probably the end of the line.

This “Lines of Sight” idea has an important implication in understanding how some of the top earning hotspot/antenna combos are doing so well. The hotspot Docile Bone Pony* (when this was written, one of the highest earners in the world) is on top of a 16 story building in a major city with a medium/high gain antenna (8 dbi from eBay on 60′ of LMR400.) It has Lines of Sight to a lot of other hotspots, BUT those other hotspots don’t have great lines of sight to other hotspots around ’em.

That means that DBP is seeing a lot of hotspots that AREN’T seeing a lot of hotspots. I’m going to anthropomorphize this a bit, but their only option is to communicate with DBP. So they do. And DBP earns like crazy. It’s an example of the incredible earning potential that exists when providing asymmetric value to the network.

While we’re on Lines of Sight, let’s talk about the range of a standard hotspot. According to some excellent work done by the inimitable @para1 on Discord, most hotspots do most of their witnessing within a 10km range. Now, an in depth discussion of the implications and restrictions of this table is beyond the scope of this article, but your general takeaway should be “Optimize your antenna for hotpots within 10 km” aka most people don’t need a high gain antenna.

@para1’s table, posted in Discord

I’ll double tap this range thing with an example of a hotspot I run, which has a 3 dBi HNTenna on top of a 20′ pole on top of a ~30′ building. It *routinely* gets witnesses over 200km away. While it seems that a high gain antenna will get you better range, it doesn’t really matter. It’s Line of Sight that is the secret here.

Finally, Lines of Sight can be blocked by forests. Depending on who you listen to, LoRa doesn’t go through much more than 60 meters of dense forest. I’m sorry rural Florida, you’ve just got a tough row to hoe on that one. Dense forest in between you and other antennas is about the only time a higher gain (up to 9 dBi) makes sense, and even then it may not make a giant difference. Forests are RF sinks.

There is one more thing to think about with Lines of Sight. The 900 MHz frequency needs some runway, ideally 50’/15m to fan out enough to diffract around obstacles. Read that again and you’ll have an advantage over everyone who doesn’t get that concept.

The concept of Fresnel zones and diffraction in radio wave communication is one of the fundamental drivers of the “RF is weird” refrain you’ll hear whenever you see a pattern that doesn’t immediately make sense. Basically, the further out your radio waves go, the more they can spread out along their radiation pattern, the less likely that all of the waves get blocked, and the more likely that at least some of ’em will get to another hotspot.

At some distance they’re so spread out that you’re basically not going to make a connection, so the effective “window” shrinks back down. Like this:

Check out RadioMobile to get deep on Fresnel zones.

If you set up your antenna so that you’ve got lots of clear space around it before it hits obstacles, those radios waves have enough spread to start “bending around” those obstacles. This is yet another reason not to set up inside.

Here’s another “I definitely didn’t go to art school” drawing to demonstrate the idea of runway and diffraction.

If you give those radio waves some room to spread out, they can get around obstacles. Let ’em breathe!

Ok, we’ve got one more thing to consider before wrapping up. Many of you will have been scouring ham radio sites to figure out how to improve the range of your antenna. Keep in mind that the goal of many ham radio operators is incredible range, but that can come at the cost of broad coverage. Doing exactly what a ham operator does may give you the results they want, not what you want.

YOU want to hit as many high scale hotspots as possible. You’ll usually do that by using a low gain antenna up high, with clear lines of sight all around.

Remember, you’ll earn the most by delivering the most valuable & provable coverage to the network. The concept is simple. The execution can be complicated. If you want help with getting the maximum value out of your placements or strategy, I’m available for hire.

For those of you who skipped all that and just want to know what antenna to get, here are 4 generally good options for the 3 most common scenarios.

  1. In a building in the city? Get an outdoor HNTenna or a McGill in the 3-6 dBi range, put it outside up as high as you can.
  2. In a building where you just can’t get up high? Use the stock antenna that came with your hotspot. Also, find a better placement location. You did read about that, right?
  3. In a suburban house? Get either the HNTenna or a McGill in the 3-6 dBi range and put it on a pole outside and up high.
  4. On a mountain where you can’t possible transmit behind you (because the mountain will block your signal) and you have an enormous view of civilization and your nearest hotspot is more than 5 miles away? Try a 8-9 dBi patch antenna, like these.

I’ll round this out with what to definitely NOT do. Don’t just look at the gain of an antenna and think higher is better. Don’t bother with Yagi antennas. Finally, don’t worry too much about your antenna. In the big picture of earnings, it is FAR more important to have good placement and elevation. The fanciest, coolest, most high tech antenna in the world won’t get you much if you’re in a crappy location down low.

  1. You can def try it. Elevation usually helps, but location is what drives earnings. If you’re locally overcrowded, location changes of 8′ usually won’t matter.

  2. Salvatore Rainone Jr.

    well if its not gonna change significantly then i rather not spend the time and money to go 10 feet higher. My second bobcat isnt set up but the location i want to put it at has the router in basement.. so i need to figure out how to get miner high up without moving router.

  3. Pingback: Why work too hard? Make your assets pay for your livelihood!

  4. My question to you is, what antenna should I use for my setup. My miner is located in Queens, NYC, and it is about 20–22 feet up right now in my attic. I would like to move it to my roof on top of my chimney. I have a bobcat miner and I use the stock 4bi antenna. Should I just get the outdoor enclosure kit and use the stock antenna or should I buy a different one? Please let me know if you need any more info!

  5. Hi Kelly, the antenna won’t make much difference; Queens is pretty overcrowded. The *best* antenna will probably be an HNTenna, but again, the local overcrowding is the big problem. You’ll be far better off moving well outside the city.

  6. Hey ? I live in a hilly town (20 min south of Seattle) that’s not fully covered but has a couple hexagons that have 2-3 hotspots.
    What antenna would you recommend for one that’ll be at the top of a 3 story house, on top of a hill that overlooks the main town ?

    – 100′ TALL TOWERS
    – SO ROGHLY 40′

  8. Good question. I wouldn’t think so, but it’s possible. Get the antenna high and you’ll probably be fine.

  9. In a one story suburban house, surrounded by many similar houses with same surroundings . Highest point is chimney ~25′ above ground. Trees 30-80′ tall about 30-40′ away from the chimney pretty much on all sides, and many trees between neighborhood houses. Have a few hotspots (all SyncroBits) with stock 3dB antennae to set up in the area.

    I’m thinking a good start would be atop a pole attached to chimney (on each house)…? But what length pole? Should 10′ be enough? 20′? Higher? Higher dB antennae, perhaps? TIA

  10. Just got my Linxdot miner today. I’m in the foothills of the Westside of Colorado Springs, with a view of the entire city. I have 2 questions:
    1. Do I need a Patch Antenna? There are dozens of Hotspots I can witness less than 5 km away.
    2. Will running my hotspot on wifi (after it’s synced of course) cause any reduction in mining rewards?

  11. Shawn, you don’t need a patch antenna, and running your hotspot on WiFi just makes it more like the hotspot will drop connection and miss out on rewards. Keep it on ethernet cable if you can.

    Hey Nik,

    Thanks for you awesome articles. Clever and humorous, always easy and great to read. I’ve been debating and reading and yours seems to give the best advice. I was even shocked to see Petite Men­thol Leop­ard I’m your article which is close to me.

    Question is: My Syncro.Bit miner only gets .01 HNT a day. My location is Napa in the foothills with a forested area. I know a antenna will most likely help. I’m thinking a 8-9 dbi would help my situation most right? I’m guessing if I get it outside on my 2 story home roof it would allow better allow Site of Vision from trees and hilly area. Would you then recommend the 915Mhz / 8 dBi gain Omni LoRa Antenna with 20ft Cable or the antenna that Syncro.Bit sells on their website? Does it make sense to buy the antenna on the Syncro website for it’s the same brand?

    Also I wanted to inquire about Helium Network Jobs you mentioned as well if there are any opportunities.

  13. Hi Patrick, the most important thing will be to get the antenna up high with a clear line of sight to other hotspots. The brand/dBi generally doesn’t matter, just try and keep it a lower dBi (5.8 is more than enough.)

  14. Guys, I have a question, I am going to place a hotspot in a very tall building – in which I have an office- in the center of a very big city -Madrid, Spain-. It is 60m- 200feet, and I’ll be able to place it outside because we have a terrace. My question is if I should go with an 8dbi, or a 3dbi. I am concerned that an 8 or even a 5dbi are to flat and don’t reach the hotspots that are directly below us (as it is a building literally located in the center). My scale is 1.00 as there are no hotspots in the “dead zone”.

    Thanks for the advice!

  15. Is an omni-directional antenna actually omni-directional? Read that theyre not but god knows how i could direct them?

  16. Hi Tommy,
    “Omni-directional” is more of a guideline; they shoot out radiation in *pretty much* all directions. You could direct them with a metal shield, and companies sell that, but there’s no great reason to.

  17. Nik,
    This article is amazing and your attention to quality and detail is superb. I ordered my FinestraMiner today for my suburban area, but can’t find info online if anyone has hooked up a HNTenna to it for boosted signal. Any experience monkeying with FinestraMiners?

  18. Hi Nik thanks for all the provided information. I am actually setting up my miner and was thinking about the antenna. Im in EU in a smaller City with smaller Hills and no Hex is attached at the moment. I will place it as high as possible and thinking about a 8 or 3db one. The next bigger City with the biggest connected Network is about 3 miles straight with a Hill inbetween. Any recommendation would bei appreciated. Kind regards Jo

  19. Yo Jo! :). Probably an 8 for now since it’s an EU hotspot pushing out much less power. PoCv11 may change all of this, so just be ready to adapt.

  20. Thank you for being so helpful Nik, the one thing I am not sure was mentioned is whether or not it’s beneficial to use a metal antenna mast or a fiberglass antenna mast to reduce RF interferences?

  21. Hi Robin, I’d go with a metal mast for durability. There’s probably no appreciable RF performance difference for what we’re doing. I’ve got clients with both options and either works well.

  22. Hey nik, thank you for your information!!!

    I am living in a City 20 km away from Frankfurt (EU, Germany). In Frankfurt there are a lot of hexs. Between my City and Frankfurt there are no Hills, but there is another City, Offenbach with also many Hex(ca.30) .Offenbach is 13 km from my city. In my City there are 12 Hex.

    My spots are about 10 m high. Would you Take a 3dbi or 8 dbi Antenna. Any rec­om­men­da­tion would be appre­ci­at­ed. I cant decide and the pocv11 makes the dessicion even more complicated.

    Sorry for my english and greetings

  23. Really hard to say for the Euro region. I’d try the 8 dBi. I don’t think there’s a great solution because the radio output is so low.

  24. Siegfried mabanta

    Hi Nik,
    Im a newbie for hotspot, please help as I no idea for the antenna range or dbi. But planning to buy a bobcat 300 with 4dbi stack antenna. My location is at a urban area with same height of houses and some small trees. Im seeing some hotspot devices near my area with a distance of at 20km and lowest is at 3km to my location. Can you recommend me the antenna i need to get more witnesses connected to my bobcat 300. Appreciate your help.

  25. Have a SyncroBit stock in my attic now, I estimate 11m height. Planning to move it outside, but can’t decide on chimney (which would allow a pretty tall pole, but is maybe 8m away from a tree on one side) or just at the roof peak at least 16m away from any trees but probably won’t allow for a super tall pole. In the US so deciding on antenna (there’s 3 different ones at the link, I presume you’re talking the outdoor US 915 one, priced at $150?)

  26. I live in an apartment on the second floor… I have access to an outdoor balcony but my MNTD gold miner is currently in my window with the stock 2.3dbi antenna. There are trees and other buildings around and my building is on a hill probably 30-50 feet up from the road. There are two other hotspots within 2 km from me but my miner doesn’t detect them, and others are about 12-14km away. Should I buy a higher gain outdoor antenna and install it on my balcony? Is this a lost cause because of my location?

  27. How much lower is the roof peak? I’d probably go there unless there’s a 5m or more difference. LoRa likes some space around it. Also take into consideration what is behind that tree that you want to hit (in terms of hotspots.)

    Yes, the outdoor 915 is the one I use.

  28. Nik, the chimney top is maybe half a meter taller than the peak of the roof. But with a huge lever arm for the chimney I could safely put up a pretty tall pole with the US 915 outdoor antenna on it. I doubt I could put up a 5m tall pole without cheesing off the neighbors though so it might only be like a 2m taller pole if I chose the chimney.

    Or I could cut down the tree.. Hehe

  29. I’d have to take a look, but it’s definitely going to block at least 25 degrees in that direction (at least as far as direct LOS). It’s “not far” from that tree. There are actually zero other hotspots directly blocked by that tree based on hotspotty, but that doesn’t mean there won’t be in the near future.

    Thinking of it, and ease of installation (because I’m going to have to hire someone to go on this roof, it’s steep and I don’t like heights to begin with), I may just do a short-ish™ pole with the antenna on it.

    Also, I see the HNTenna and notice it’s only 3db gain. The region around us is pretty suburban, and I’d be shocked if another hotspot shows up within 500m of me. But if I look out our upper windows, besides a house or two in all directions, all I can see is trees beyond those houses. In total, visible (LOS) houses from my house is maybe 30 houses because the trees are so mature around here, not to mention we’re bordered by a (forest) park.

    Should I consider going for a higher gain antenna in that case? I presume dipole of some kind? I mean, my best bet would be to put up a 30m tall pole, but…

  30. Height will be more important than antenna. In a highly treed area RF at our freqs is generally hard, so elevation will be your best bet. PoCv11 should even out the playing field for everybody, but it also means it’l be harder to get actual useful gain out of an antenna.

  31. Great info. You seem like to like helping people. 🙂 When I ordered my hot spot there were no others in my ‘red zone’. However now, 5 mos later, there is one… however, there are also more now in my area overall and 3 in my ‘sweet spot’.

    My question is I know the one in my red zone will cut into what mine earns but will the other ones in my sweet spot maybe make up for that? Asking b/c I do have a ‘host’ who is willing to let me place it at his house (none in his red zone) . Similar terrains, neighborhoods, homes, trees, and number of hot spots. I prefer it ay my house but not if having 1 in the red zone really does cut into rewards. Not hooked up yet… just got it. Thanks so much for your great info!!

  32. Hi Nik, or maybe someone know… I have a question about length of cable.
    I bought Bobcat and I need to buy outdoor antenna for miner, also cable for antenna with 40 meters length.

    1) can miner work with 40 meters cable between antenna and miner
    2) what type of Antenna I need
    3) what type of cable I need

  33. I live in a pretty secluded area with a couple of green hexes. Although they have no witnesses not too far from me. Woodsy area with some hills and lakes. I am trying to decide between a 5.8 DBI & 8 DBI this will go outside high near my roof. I am torn on which one I should get. There is a city with a ton of hexes and witnesses about 26 miles from me.

  34. Hi, I have ordered a bobcat 300 miner and I like to ask you about the antenna cable length. I understand that the length of the cable is 1 meter that comes with the miner. If I use a different antenna what is the maximum length of the cable I can use in order not to have a signal loss

  35. Hi, thanks for the great info. I have a 5.8 antenna and was wondering if mounting it to a wall or in front of a window is best? This is on the 2nd story of my house. I do eventually plan to roof mount once I can get access.

    Also, I recently reinstalled the stock Rak wireless miner antenna too as I lost about 50% rewards for the week the 5.8 was connected and wall mounted. The unit with stock antenna was sitting in the window previously.

    Witnesses with the 5.8 dropped as well. Went from 13 to 8.

  36. Hi Nik,

    I am trying to trouble shoot for my brother in the Austin Texas area. He has a nebra outdoor and is unfortunately a bit far north of the city in Leander Tx. I imagine it as if he is really far from other hot spots and wants to reach the others towards the city so based on what I read he probably wants a mid to high gain antenna pointed specifically in the direction of the city until the network grows out north closer to him. Would this be the right train of thought and do you have a recommendation on antenna ? Thanks

    I am currently using the 4db antenna from Bobcat (about 2m High) and am wondering whether a 5db omnidirectional antenna (https://www.wimo.com/de/18003-868) or another antenna would make sense.

    There are tall buildings around me
    Or does it make sense to put a 2nd antenna over a splitter in the backyard?
    My building is made of reinforced concrete
