This is written for folks curious about optimizing a Helium Hotspot placement.
Most start with their antenna, which is (almost completely) the wrong approach for maximizing earnings. The only way you could make a less efficient improvement at the start is to focus on what cables to buy.
There are four fundamental aspects of an optimal Helium hotspot placement; antennas and cables are at the bottom of the list for importance.
Before we get there (relax, it’s only a few paragraphs away), let’s get a few important points out of the way:
First, while I think everyone reading this should buy at least one hotspot and place it as optimally as you can, over the long run you’ll earn far more by figuring out a way to actually use the network and not just provide coverage.
Second, if you follow and read through every link in this article you’ll be ready to make excellent decisions about the best possible hotspot placement. The whole thing (Helium, antennas, optimum hotspot placement) will take about an hour to digest and understand.
Third, if you don’t want or have the time to figure out Helium on your own, you can take a course or hire me.
- You know that Helium is a network of Hotspots that transmit and receive radio signals, then pass those signals onto the internet. In general, the more signals a given hotspot receives, the more HNT it earns. Hotspots record all transactions on a blockchain and reward owners for providing coverage with HNT, a cryptocurrency token.
- You have, or have ordered, or are thinking about ordering, a Helium hotspot.
- You haven’t read every last post and thread on the internet about maximizing a hotspot placement. 🙂
There are only a few things that really matter when it comes to your hotspot placement. Some of them will change over time, some of them are fundamental. All are driven by just one goal over the long term:
ADD VALUE TO THE NETWORK
FUNDAMENTALS FOR OPTIMUM PLACEMENT
In order of importance:
- HOTSPOT DENSITY
- ANTENNA “VIEW”
- APPROPRIATE ANTENNA
- MINIMIZED & HIGH QUALITY CONNECTION LENGTH/CABLES
HOTSPOT DENSITY: Optimum density is determined using Uber’s H3 map. At the low end, hotspots won’t earn from other hotspots less than 300 meters away. At the high end, hotspots can “witness” other hotspots 50 km out.
Back to the Uber map. The map uses (mostly) hexagons to form grids of different sizes. Each size is called a “resolution” or “res” for short. Each hex size has an appropriate density for its resolution.
Here is a dated interactive map (it stopped being updated in late fall of 2020) of density and hotspot placements. It’s color coded and fairly intuitive. Green means good density, red indicates too dense. Here’s a quick screenshot:
At each “res” there is an optimal number of hotspots per hexagon. That number can change. It is determined by a base rate of hotspots per hex plus the number of hotspots in surrounding hexes. Go ahead, read that sentence again a few times. The details are in HIP 17, look for “Proposed Chain Variables.”
Yes, it’s a bit complicated. It was made this way in order to programmatically account for density differences between cities, suburbs, and rural areas.
Here’s a screenshot map of San Francisco (pulled from the HIP 17 Visualizer) to give another perspective.
Notice the green hotspots don’t have other hotspot as close to them as the orange and red ones. Red is the worst; they’re basically on top of each other and providing duplicate (or triplicate or worse) coverage, which isn’t useful to the network.
If you want to know if your location will be good, you’ll need to study HIP17.
If you read HIP17 until you understand it, you’ll be in the 1% of Helium Hotspot owners who don’t really have questions about optimum density.
It looks complicated at first, but it’s actually straightforward. If you’ve ever read about Goldilocks and the 3 Bears, you’ll have an understanding of hotspot density: Not too dense, not dense enough, but just right.
If you need to visualize things, use HeliumVision or Hotspotty. Use the options for hex overlays in HeliumVision or just zoom in and out on your Hotspot with Hotspotty. If you need help with HeliumVision, consider taking my HeliumVision Master Class.
If you don’t have the time or just want to skip that part, you can hire me and I’ll help you pick the best option for your area and circumstance.
BOTTOM LINE: You need to have optimum density for maximum earnings.
ANTENNA VIEW: Before you go ordering the latest and greatest super-hot antenna (more on that later), make sure your antenna has a view. A “view” has three important aspects.
- Outside. Walls and even windows will block radio waves.
- High above other obstacles.
- Clear view to as much as possible.
The view of your antenna is far more important than upgrading your antenna. A higher elevation “stock” antenna (the one that comes with your hotspot) will outperform a super fancy antenna that’s low down EVERY TIME. You can see the line of sight of your antenna to specific spots using RF Line of Sight or Helium.Vision.
Get as high as reasonably possible. How high? From the American Radio Relay League’s document on antenna placement:
“To a distant receiving station, a transmitting antenna at 120 feet will provide the effect of approximately 8 to 10 times more transmitting power than the same antenna at 35 feet.”
You may be thinking, “I’ll never get my antenna 120′ high.” That’s OK, do the best you can, but know that until you get it high, you’ll be missing out on earnings.
A good rule of thumb to start approaching 90% of optimum earnings is at least 20′ above your roof and surrounding roofs.
Here’s an example of a good elevation placement:
That antenna is on top of a 23′ pole on top of a 15′ high roof in suburban San Diego.
Anecdotal reports show that even a *1 meter* elevation difference can noticeably affect earnings.
Get as clear a view of as much “civilization” as possible. Remember, the network is only as valuable as the USEFUL area it can cover. A hotspot on top of a mountain with clear views of nothing but nature for 30 miles is not covering (to the network, anyway) USEFUL territory.
A hotspot on a suburban roof surrounded by a few million people and lots of data opportunities will provide far more useful coverage.
Correct elevation is vital for maximum coverage. LoRa is more or less a line-of-sight radio technology. While the radio waves will go through a few things (a wall or two, a window, or a leafy tree), for the most part you want to be able to have a direct line of sight to both your coverage area AND other hotspots.
APPROPRIATE ANTENNA: The antenna is what most people focus on, thinking that if they just have the “best” antenna they’ll make the most HNT.
The antenna shipped with any purchased hotspot is already pretty good. However, as many Heliites are both tinkerers and driven by earnings, many will “upgrade” their antenna in order to reach more hotspots.
Antennas do 2 things: They transmit (tx) and they receive (rx). Most folks get wrapped up in how well an antenna transmits, but in the long term that doesn’t matter that much, as the value of Helium is in how well an antenna can RECEIVE.
Remember, the Helium network offers value by being able to receive transmission FROM sensors TO hotspots, then push that information onto the blockchain via an internet connection.
While there is and has been a place for being able to transmit powerfully, that value will diminish rapidly over the coming year.
What the heck is “dBi”? It refers to the focus and shaping of the energy an antenna transmits and receives.
Here’s a quick dbi gain visualizer:
I can hear you now: “Ok dude, but what antenna should I buy?”
You can read this in-depth article on how to match your placement with an antenna, but you’ve basically got 3 options.
First, and recommended: Don’t buy anything, just use the antenna your hotspot came with. Get your density and view squared away first.
Second, if you’ve got a great placement with the right elevation, buy either an HNTenna or anything in the 3-6 dBi range from McGill.
Third, if you feel like you need something higher gain and you understand the trade offs of a higher gain antenna, get a higher gain antenna from McGill.
“But, but, what about the [insert fancy antenna] I read about on the Discord chat? Shouldn’t I get the most powerful antenna possible? I want more money!”
No. Re-read the above piece on having a “too powerful” antenna.
The one pictured above is a high gain sector (directional) antenna on top of a mountain. Despite having an enormous “view”, it does worse than many placements that are much closer to other hotspots. I replaced it with a 3 dBi omni, no difference in earnings. Density matters more than antenna.
Even “hot” antennas that are tuned to fit within Helium guidelines (decreased transmit and receive power) won’t radically outperform other antennas.
One Hotspot owner I know ran a Nearson 9 vs a Rak 8 dBi in early 2021 and kept track of earnings between the two. The RAK beat the pants off the Nearson.
MINIMIZED CONNECTIONS: Ok, now we’re coming to stuff that doesn’t really matter but you’ll ask about and geek out on anyway. How should you connect your hotspot to your antenna?
This is RF 101 (Radio Frequency): You want a thick, clean, short (ideally 5′ or less) cable that goes from your hotspot to your antenna. I recommend and use LMR400 from USACoax.
If you’re running a cellular backhaul you’ll probably be fine with another LMR variant for the cell antennas (each setup is unique) but you will want to place those cell antennas external to the enclosure.
Get your hotspot up high near your antenna to keep cable runs to the antenna short. Run power and ethernet to the high hotspot, then have a short antenna cable to the antenna. Do not (if you want max earnings) place your hotspot in your attic then run 20′ of thin crappy coax cable to your antenna. That will create more radio power loss than you want.
If you MUST have long cable runs, spend the money on good cable. If you do that, you may (but probably won’t) get the same results as Docile Bone Pony, which uses 60′ of LMR 400 and is on top of a 16 story building in the middle of a large city.
So. That’s most of what you need to know about a optimum hotspot placement.
What else should you know about when it comes to Helium hotspot earnings?
How much HNT you get per witness/beacon transaction will change as the network develops more fully. With a limited amount of HNT made available (2.5 million per month until August 2023, when it drops to 1.25 million/month) to reward transactions AND many more hotspots coming online in the next few months, earnings will steadily dilute.
Yeah, but how much can I earn? Check here for a very rough estimate. This can change significantly, so it’s just a starting point.
No matter what, with the growth of the network your HNT earnings will CONTINUE TO DROP.
This MAY be offset by an increase in HNT price. It may not.
How can I earn even more? The long play with Helium is to figure out how to actually use the service. What kind of data can you collect, what kind of sensors should you use, how can you offer that as a service?
If you want help with that or with optimizing your hotspot placements, I’m available for hire.
How much power and data do hotspots use? Hotspots use about as much power as an internet router, and as much data as heavy Netflix user who watches 2 or 3 movies most nights (100-150 GB/month). This will continue to increase until Light Hotspots come online sometime in early 2022.
If you live in the First World and have a broadband internet connection, having a Helium Hotspot will be basically unnoticeable to you from an energy cost/data use perspective.
I’m ready to buy a hotspot, where should I order? I’d recommend ordering a hotspot from ParleyLabs.
Is there a difference in hotspots/miners/radios? Not really. It’s not like you can get a more powerful miner that’ll earn you more. The biggest difference is when they’ll arrive, which is a function of how fast they can be manufactured.
Is it really worth it to put up a Helium hotspot? I sure think so. Will it be for you? If you have an optimal placement and follow all the advice above, probably. This isn’t investment advice. You could lose all the money you put in.
How much can I make? If you do a good job, between .5 – 1 HNT/day as of March of 2022. More on that here. Or just go to Sitebot and start poking around to see what the current maximums are.
How do I turn HNT into cash? Open up an account on Binance.
Is this a safe investment? No. This is cryptocurrency competing with giant telcos (Telecommunications Companies). It may be a boomer (like when Uber competed with cabs or Airbnb competed with hotels) or it may be a flop (like every other startup company that tried to take on the big dogs.)
You should not re-finance your house to put up hotspots. You should be able to lose all the money you put into hotspots without putting yourself, your family, or anyone you know at financial risk. Sheesh.
Should I just hire you to do all the work for me? Maybe. If you don’t like to read or geek out, or you just want to try Helium without spending a few months researching it, I’ll walk you through the process of setting up the best possible placement for your situation.

Right on Arun, glad you’ve found it all useful. Keep charging!
thank you, great insighting points.
Good stuff. Thank you very much. I wish I had an antenna expert to mount an 8 dBi antenna on my roof, and also guide me how to get out of my Bobcat 300 miner with RELAYED STATUS. Can you recommend a person in the Chicago Suburbs area? Thanks a million
Any local electrician or satellite dish installer will be able to mount your antenna. As far as getting out of relay, it’s more a question of doing it right and then not relying on Helium Explorer to check your work, but rather Helium.Status.

Do you have any concern a large antennae like that on the top of your roof makes you a target by potentially broadcasting to the passerby you’re miner?
Sure, it’s definitely an identifiable thing. Not sure what to do about that; I just leave mine up high and let ‘er rip.
Hello first I want to congratulate on such a good video. I recently got into helium mining and there is a couple things I cant seam to wrap my head around. I live in a small town and there is already around 8 helium miners set up, but fairly spread out. The ones in the central area are mining around 2HNT monthly, then there are 2 that are placed almost in the middle of nowhere and are mining 15+HNT monthly.
This is really making me question where I should chose a urban area with plenty condos or just plain suburbs.
Could use or opinion on this one!
Thanks Francisco. I’d recommend using HeliumVision for assessing locations and making those kinds of decisions. I’ve built a Master Class for using HV; it’s powerful but can be complicated. Rock on!
Hey Nic thanks for this. Super helpful!
My question is more about devices. I’m in Africa and curious about how to know if you’re getting a legit device or not. Can I build my own? Or buy from anyone building raspberry Pis and just configure it to connect to HNT? Or does HNT only allow approved devices to connect to its network? There are a lot of resellers entering the market and trying to figure out how not to get scammed. Thanks!
Helium only allows approved devices to mine HNT; you can’t build your own. I’d start on Helium’s page about approved hotspots/makers.
Thank you for all the information you are sharing with us.
I have one question, in a few days I´ll receive a new device (Pisces P100) and I want to locate it as good as possible.
I´m living in a 7th floor flat (from 8, 20m aprox. from the floor) with a balcony, where I´ll instale the antenna.
My question is, in a balcony you don´t have 360º view (maybe 180º-220º), do you think it can be a big disadvantage?
Not a huge disadvantage. Just get the antenna outside and you’ll usually do much better than if it’s inside.
I must have read this article a hundred times and it’s spot on with exception to recommending Parley Labs. After this last Nebra update I really hope you all take your business elsewhere. I didn’t think Nebra could be beat for poor service but Parley holding my funds for 10 months and then offering a consolation prize is a slap in the face. I’m sure this will get deleted but this is still a comment for the Helium Network and a red flag posted for future miner purchasers. Good luck all!

Im in a area with very few hnt hotspots at the moment. Theres 1 at approx 3 hexagons away, others are even further away.
Im have also on 2 sides big cities at 25km away. How important is it to connect yo those cities with plenty of hotspots in comparisation 2 close coverage in my own Town with only 2 other hotspots in the Town it self.
As i understood, coverage is more important than distance, but its hard to change the mind thinking i could ezrn more by being able to connect to the big cities, instead of coverage where not a lot people use allready helium.
Do to specify more. Im located in a hexagon without other miners, closest miner is at 1km approx to connect with, 1 big city in the north of me at 20km, 1 even bigger city in the South of me.
Could you please give some advice on how to upgrade my situation. Im not connected yet, but im looking first to get all the boxes correct.
is the loss you experience when using long cables really that much of an issue? I don’t have electricity in my Attic, so I am planning getting like 5m long cable(lmr 400) from my window to the top of my roof. Do you have a better solution? Thanks 🙂
Hi Darius, you can just calculate it using any online calculator. In general, 5m of LMR400 is not a big deal.
Hi, Where you buy and what is the model of this 23 feets pole. i would!!
Local metal shop, 23′ of .095 4130 steel IIRC.
Do you have any cable recommendations for a flat cable to run through my window so I can get my antenna outside? I am aware of losses but I believe the benefit of having it outside outweighs losses in the cable. And I am in an apartment so my options otherwise are limited (i.e. non-existant). I’ve been researching but I haven’t found any YouTuber who sounds remotely intelligent who has covered this and I struggle to trust any random source.
Sure, try this one.
I have watched many of your video and read this tutorial multiple times. I will be mounting both of my Nebras this weekend using a 30′ pole on one of my peaks (27′). After the 2′ loss for the bracket, I should reach about 55′. I will be using 3’of LMR400 and mount both Hotspots in an outdoor weatherproof box 52′ in the air. The boxes will have 2 fans each with a thermostat and an IOT thermostat and humidity reader that will use the network for monitoring. My area is awesome and HotpotRF says I should be in the 12-14 HNT per month range. While there are more Hotspots being added in my area, it is rural and I hope to reach into the city with my 8.5 dbi antennas. My question is this… Should I have one fan blowing in and one fan blowing out, or both fans blowing out? They will have vent covers.
I have seen arguments on both sides. Also, I will have silicon packs inside of the boxes to catch any humidity that will find its way inside. Thanks for your time and awesome teachings.
Don’t need both fans & dessicant packs; they dessicant packs will quickly saturate and be useless. 1 fan blowing is fine, either in or out.
Hello Mr Nik , I really appreciate the info here . I just started mining helium. My location is excellent in all resolutions except 1 the ” too many devices” resolution 4 . If I move my placement 600 meters I will gain 1.00 on that too but will that be too much I read here and there the most is 300 meters. Thank you
First of all, love your site and your knowledge. Far superior than most sites out there. Question – with these metal poles so high up, what do you do to protect against lightning strikes?
Hi Will, you can’t really protect against a direct strike, but you can add a “lightning arrestor” that’ll dissipate the static charge before it hits your expensive equipment. I cover that over here. Rock on!
I live in MN and am wanting to put my Bobcat 300 in an outdoor enclosure. I’m looking to get it 20-30′ above my roof. I’m wondering what kind of enclosure to use based on weather. Our Summers can be hot (90s for 2-3 weeks) & more so very humid. Our winters get cold, below 0 Fahrenheit. Do I build an enclosure with a fan & vent to circulate air in/out OR should I keep it sealed to keep the humid & cold out?
Great question! I’d add heat sinks to the Bobcat, put it in a sealed enclosure in the shade, use dessicant packs and monitor temp & humidity with an LHT65.
Thanks NIK! One more question. I’m in the northern suburbs of Minneapolis. Downtown is 10 miles away, with a pretty straight line of site once you get over the trees. I’m working on getting my miner up 25′. I saw a diagram somewhere that a 3Dbi antenna will reach out 20 miles with a straight line of sight, is that accurate? I’m going with your advice and just going to try the stock Bobcat antenna and see what my results are before plunking down big $$ for an antenna.
Yep, clear line of sight & 20 miles with a 3 dBi is totally doable.
very informative set of blogs. i recently got my miner (sensecap) and am following your suggestions.
it earned some small amounts 24 hours back but nothing since. it has gone online only 2 days back and helium explorer says its still syncing.
the sensecap dashboard says its 100% synced.
i guess there is some delay on helium explorer but is there any effect on earnings?
is there some delay in when the hotspot starts to earn?
Yep, Helium Explorer can be delayed by a day or so. Use HeliumStatus.io to get up to date info.

hello, https://explorer.helium.com/hotspots/hex/882c2026d7fffff in this hex is two person and both have 1.00 transmit scale, in my hex two person too but I have 0.50 why, is this normal? about distance in first hex they have distance 205meter and have 1.00 about my hex we have distance 260meter and I have 0.50 please tell me why
Hi Dave, check this post to learn how scaling works.
Hi Nik, I hope you don’t mind a couple more questions…. I have researched myself but am getting conflicting information… a while back you were very helpful to set up a miner with a friend in a potentially better location. We managed to get the miner running but in the 6 weeks or so it’s online it has not witnessed any hotspots at all although it is earning…. Though in 30 days 16 days did not earn… the surrounding area has plenty of good hex with mainly 1 transmit scale ( as have I ) I have clicked on hotspots and I found my hotspot had been witnessed by a few. Sorry for long message I suppose I would like to know how much impact my zero witnessing has on earnings and maybe a link to read more on optimal placement and also maybe you can send me information about the paid support you offer to see if it is a possible option for me. Thanks and apologies again for length of message ( I really mean it when I said that your information is the best I have come across) Cheers Bill
Bill, it’s hard to say why your hotspot isn’t earning. The Network has been pretty spiky for the past few months as far as earnings, so you can have everything right and still not get the rewards you think you should. I wouldn’t do the paid support for that; as long as your Hotspot is plugged in to power and connected to the internet you’re doing everything you can do. Take a look at this in the meantime if you haven’t seen it: https://gristleking.com/hip-17-why-are-you-getting-scaled/
Thanks Nik, it’s more for my mate I’d like to see a bit more earnings. To be honest I’m more interested in the tech and the future possibilities. I have been really getting a lot from your YouTube videos. I’m also interested in the possibilities for using the technology and am keen to find out more about sensors. I watched a video last night with you and some others. Am I right in thinking the lady from Bobcat was talking about a way to chat to others in your area and would that be a way of helping people get their hotspots back online etc…. Do you think that if you are near too many relayed or inactive hotspots it will effect people in the area. Before i moved my hotspot from London in a hex with 9 hotspots 6 needed attention and I thought if you could communicate with them and help them it could help everyone. Is that what she was talking about… love your positive attitude keep it up
Thanks Nik, very helpful. No doubt ill be in touch when my miner arrives as I’m 45kn from the next spot.
Hy Nik, I just begun with a merryloT. Should I open the port 44158 now a days?
Nope, leave it alone. We’re past that particular requirement. Rock on!
