Antenna: RAK 5.8 dbi, Cables: 11 LMR400, Nice Lipstick Chimpanzee Elevation: 25 above ground, Area: San Francisco, CA.
Pretty neat, right? Thank you for help. second issue is placement of hotspot. Ability to troubleshoot a helium installation to verify is the antenna coaxial cable and Antenna are working or rule out if the issue is the hotspot. Ultra Low Loss 75 Ohm Coaxial Cable The LMR Range, Times Microwave Systems Registered trademarks, Times Microwave Catalogues and Data Sheets. Also, and sorry if you had already addressed this, but would the connection from a wi-fi signal (the signal is coming from an extremely stable 4G connection from a router) be much worse than ethernet? Waterproof and high temperature electrical tape, Analysis of an Isolated Cluster of Miners for SORMN, Way to Gain High ROI for Helium as Space gets Crowded: Single Owned Rural Miner Networks(SORMNs), Antenna mounting poles(check Amazon for a suitable one). Ok, lets start with broad strokes: The antenna you choose for your hotspot placement should match your topography, your elevation, and your lines of sight. Not near any cell tower and antenna is high above the roof lines in a suburban neighborhood. In this well focus on the choice of antenna to maximize the earnings. That means a 6 dBi antenna will give you 33 dBm of EIRP with a US hotspot. Your email address will not be published. Remember, youll earn the most by delivering the most valuable & provable coverage to the network. I really feel that it would improve my earnings as currently, I have it set up inside next to a window. Topography refers to the buildings, earth, and water that surround, channel, and block your radio signals (propagation.) Dont worry so much about the right antenna. McGill Microwave Systems are a team of highly experienced RF engineers with a combined experience of over 60 years. The Helium network is the fastest growing decentralized LoRa network in the world. While it seems that a high gain antenna will get you better range, it doesnt really matter. The concept is simple.
Area: San Francisco, CA. That brings us to ELEVATION. Cities in general do not have a flat topography, even if theyre built on flat land. They are also a popular choice for internal or external window mounting applications as an upgrade to the stock antennas supplied with the hotspot. No antenna will blast through hills.
Ability to connect multiple antennas to the hand held tool, one after the other and records instantly which antennas witnesses the most hotspots in your area. I had 4dbi antenna for 2 days and then swapped on 6dbi 2 days ago but I can not see any difference in witnesses, rewards etc. Finally, dont worry too much about your antenna. Still, most people dont live in the desert, and the flattest state in America has a ton of trees on it. This alternative antenna design is known as Directional /Panel antennas -also known as Sector Antennas. . study done in 2012 on a wide swath of building materials and focusing on the GSM 900 MHz band, American based hotspots start off by pushing out 27 dBm. Since the PoCV11 changes introduced by Helium which reduced the Hotspot output power to +14 dBm in the UK/EU, McGill Microwave have experienced a significant upturn in demand for our higher gain 7.5dBi and 9dBi Tuned and Optimised Omni Directional Antennas. 7 day minimum to get good numbers. We are also very active in commercial telecommunications applications in the Oil & Gas, Rail, Marine, Medical, Automotive, 5G and last, but not least, the Helium/IOT marketplace!

While it looks huge and cool and rad, it is the wrong antenna to use for these deployments. This Lines of Sight idea has an important implication in understanding how some of the top earning hotspot/antenna combos are doing so well. Hi Lyubo, fine to set up the stock Bobcat antenna outside, I believe its outdoor rated. Provides the ability to send a beacon from any location and record the amount of witnesses for a given potential hotspot antenna location. However, given the unique application here of Helium and the desire to connect with all hotspots irrespective of location, the McGill Microwave higher gain Antenna design are completely unique in that we have designed these antennas to push more power into the sidelobes of the main beam giving the McGill Antennas a clear advantage in still being able to connect with hotspots much closer in, while still covering long range.
If you give those radio waves some room to spread out, they can get around obstacles. These static build up can be bad and any ham radio operator knows the trouble they can cause.
You can post and find jobs there, help support the ecosystem by making it easier to connect professionally, and let the world know thatYOUexist and want to help contribute within the Network. Thank you so much for your hard work and support to the community, Im looking for the SenseCAP M1 hotspot EU868 Ok, weve got one more thing to consider before wrapping up. Every increase of 10 dBm has a tenfold increase in power. Making sure the location of the HotSpot is an adequate distance away from any other miner. what would be the best? Any decent brand from 6-9 dBi will do as well as anything else in the location youre describing. At some distance theyre so spread out that youre basically not going to make a connection, so the effective window shrinks back down. Remember, location is FAR more important than antennas. There is one more thing to think about with Lines of Sight. Height is King is what the McGill team often say when working with clients on optimising setups. The McGill 6dBi tuned antenna has a vertical beam width of 35 Degrees. Use the stock antenna that came with your hotspot. https://explorer.helium.com/hotspots/1121aRSBSxheung9eFVStXmcV3hsyjU6wcWYkhUNeVGBD8H1qPKh, hi. There are also locations that may be much more suited to a different type of Antenna design compared to the much more common Omni Directional Antenna designs used by the Helium community. Finally, Lines of Sight can be blocked by forests. Copyright 2022 Gristle King Inc. All Rights Reserved. Read that again and youll have an advantage over everyone who doesnt get that concept. Since changing from our Omni-Directional antenna in this location, it contributed to an increase in the rewards by around 30%. My Bobcat isnt sending or receiving any info. All those spiky buildings sticking out will gobble up your radio signals. You did, On a mountain where you cant 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? Ok, so thats earth. You may check out your location on the Helium Explorer Coverage map and think youre perfectly positioned in regards to nearby hotspots, like this: See how that spot is tucked into a bunch of hills? I have no red lights nothing. 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. This may be true in some cases, but various locations require different antenna gains (both low and high) to achieve optimum performance. Establish what the best location is for a hotspot. However, the use of 2dBi antenna provides a better coverage. So don't go around buying antennas without considering the location well. Testing different antennas has always been the path to optimisation and continues to be for many.
Its up high with a higher gain antenna, and in general, inaccurately aimed over most of the nearby hotspots.
would that matter around hills?so can 6.5dbi reach higher over the hill then 8.5dbi?Am i understanding right? Thank you for your response. I havent used a signal booster on any of my setups so far, and some of them are miles from the nearest Hotspot. Area: Englewood, CO. Antenna: RAK 8 dbi. I wouldnt worry about it, but only testing will tell. However, there is a brand new hand held Helium Analyser field tool now available from McGill Microwave Systems which, for the very first time, now enables the user to answer the question themselves of Whats the best antenna to use for my Helium Hotspot location. The picture below show some of the most common antenna dBi in the market and their RF coverage. Which one should be the best in my case? Run 40 or less of LMR400 cable to it from your hotspot. Cables: Bingfu, Petite Menthol Leopard Elevation 25. Only a lightning conductor can do that- Warning to make sure your antenna is in place that is not prone to get hit by lightning. Optimised Helium Antennas All Questions Answered! Pingback: 5 Plug & Play Income Ideas 2022 | Crypto Gem Tokens. Lets keep this less technical and to the point. I would probably put it on 10 meters (+- 1-2 meters). Check the YouTube interview with Matthew Patrick for more on collecting good stats for Helium related decisions. The concept of Fresnel zones and diffraction in radio wave communication is one of the fundamental drivers of the RF is weird refrain youll hear whenever you see a pattern that doesnt immediately make sense. If you take the bulb by itself, the light spreads everywhere with less intensity, but when you put the bulb inside a flashlight, it focus the light into a specific direction with higher intensity. and check by your country to make sure which frequency is compatible. How to Choose an Antenna for Your Helium Hotspot? Does that make sense? In the big picture of earnings, it is FAR more important to have good placement and elevation. The results are a little skewed because of that. This is my location https://explorer.helium.com/hotspots/hex/881ec152b7fffff As visible here, the location of the HotSpot relative to the other buildings makes the use of a 9dBi antenna not suitable, since the RF coverage goes over the rest of the building. Just keep it by the window overlooking outside.
That means that DBP is seeing a lot of hotspots that ARENT seeing a lot of hotspots. Water allows radio signals to travel much further than normal; look at any hotspot next to a body of water and youll see it will connect with other hotspots at much further ranges across the water than it will across land. We use cookies on our websites for a number of purposes, including analytics and performance, functionality and advertising. Imagine your antenna is a torch, emitting light from it. Area: Bayonne, NJ Antenna: Stock 3 dBi Cables: 1m pigtail, Warm Juniper Panther Elevation: 4th floor rooftop.
A Rough Guide To Helium Hotspot Placement, 5 Plug & Play Income Ideas 2022 | Crypto Gem Tokens, https://explorer.helium.com/hotspots/112gw67DtWkv9oK6kGi3EX2LnKZPAU4D5AeYR1EtF8P42sfamUsW, https://explorer.helium.com/hotspots/hex/881ec152b7fffff, https://explorer.helium.com/hotspots/11e9gtZYsxr1EE42SdipydLU6Ti3PJVXpdNRqAZv3W8XFRwBqgZ, In a building where you just cant get up high? Hi Martin, Lets analyse the below Directional Antenna and its placement, Good Location Better Antenna Choice McGill Microwave 13dBi Directional Panel Antenna. Here is a step by step method for understanding how to choose the best antenna for your hotspot placement. dBm is based on a logarithmic scale. Will it affect the performance on the antenna if the info is not updated correctly to reflect proper DBis? Antenna: RAK 5.8 dbi, Cables: RAK pigtail interface converter bundled with antenna. 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.) Still, you can see why in *most* cases, you want a low or medium gain antenna up high. UPDATE: HeliumVision now reports this for all hotspot owners who have entered this on Helium app.
But getting an outdoor antenna and placing it outside reduces the barriers mentioned earlier and that generally makes an outdoor antenna more useful. Unless you put up an antenna thatll stick over the top of the hills, youre restricted to witnessing only other hotspots in your immediate area, and in this case, that area is small! what do they max out at? regards. Remember, topography includes not just hills, mountains, and water, but all the buildings, bridges, and other structures that might block your radio signal. Light Hotspots should make this a thing of the past. If you want help with getting the maximum value out of your placements or strategy, Im available for hire. Making sure the location of the HotSpot is an adequate distance away from any other miner. It has Lines of Sight to a lot of other hotspots, BUT those other hotspots dont have great lines of sight to other hotspots around em. However, to achieve this efficiently the dBi of the antenna should be higher. Helium Explorer is a great tool to determine the location. regards. Press question mark to learn the rest of the keyboard shortcuts. It can record the receiving hotspots individual RSSI received power level and SNR Signal to Noise Ratio levels for a given tested Antenna. Second, for those of you who just want AN ANSWER: Simple: Pick up one of these if youre on a budget (use code GRISTLEKING to knock off another 5%), get this if have plenty to spend or choose from the McGill selection. I want to get Senscap M1 with antenna but I dont know which antenna shoud i get Ill round this out with what to definitely NOT do. Learn how your comment data is processed. Many of you will have been scouring ham radio sites to figure out how to improve the range of your antenna. Tuned & Optimised 13dBi Directional Panel antenna, Choosing The Best Helium Antenna For Your Hotspot. Hey Nik, Youll probably be best served with a 9 dBi, just get it up as high as you possibly can. You can also run that idea backwards; if youre in a really flat area where you dont have a lot of obstacles, a high gain antenna might be your best bet. 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. All of the above information is fed back through the Helium system and into the Glamos Walker APP via the Helium console where you can display all the information. You dont need to. Seeing many things online and getting confused as I dont want to spend too much so what would be my best options, https://explorer.helium.com/hotspots/11ADQM15ioZM4KnQoTG7sUAfFe73mox61fdSpZmzUFQcFXKjxyy, Higher gain antenna probably wont do as much as getting your antenna outside and up higher. Hi nik this my location and i want your advice which antenna you recommended to use This allow light to reach further out.
Hey Nick, quick question. hi. Dont bother with Yagi antennas. That means if youre INSIDE the building, youve burned most of the energy of the antenna just getting outside the walls. Two key things that determine the earning potential. European and other areas start WAY lower, at 14. https://explorer.helium.com/hotspots/11e9gtZYsxr1EE42SdipydLU6Ti3PJVXpdNRqAZv3W8XFRwBqgZ, I just want to know where to get the equipment your using. Kind Infrared Lynx Elevation: 15 above ground, Area: Denver, CO. Antenna: Taoglas 8 dbi. The antenna choice is related to the topography and the distribution of other miners - how many, how close or far and line of sight in between, not the device. Earth = No Radio Waves Getting Through. 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. Do NOT, by the way, try to get the giant antenna in the picture below. 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. McGill are also good antennas. From the above discussion, it can be seen that, until now, there is no one obvious selection for a given location. or the 5.8 dBi to go through the few threes and many cars ?
is that normal?or should I wait a few more days? This is only partly the reason why McGill antennas are the most sought after in the industry today. I mean, not for the hotspot owner, but its a neat demonstration of the concept. McGill Microwave Systems are perhaps best known globally in the Helium/IoT community for our best-in-the-world McGill Antennas & Ultra Low Loss, High Performance LMR Coaxial Cable assemblies. Amplifiers? in town 4 miles away from me there are hotspots which are working fine but the town is at altitude 200-220m, there is a chance to connect with them but what antenna should I buy? Cables: 15 LMR400, Lucky Dijon Scallop Elevation: 33 above ground.
Like this: If you set up your antenna so that youve 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 indeed a bonus and can be seen in the picture above this Antenna is witnessing like a combination of a traditional 360 degrees Omni Directional Antenna as well as a focussed long range Directional antenna. How much will buildings block or reduce the power of radio propagation? We decided that this Directional antenna may prove to be the ideal choice here because this is a location where you have minimum hotspots behind (North of) the location. Lets go through 3 examples. I spent a fair amount of blood and treasure to learn that lesson. Canada Distribution Open Now Doing exactly what a ham operator does may give you the results they want, not what you want. Look at the scenario below. Put it outdoors at least 10 above all the buildings around you. 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. Now youve got to calculate cable and connection loss. Hopefully the above article has given a basic overview to Antenna selection which the reader finds helpful. Hi Georgi, I think youd be fine with a McGill 6 or maybe higher. Thank you and welcome :). I recently got my Bobcat 300 and was wondering if it would be safe to put the stock antenna outdoors on the roof for example for better coverage. So it would be smart to get a ligthning arrestor and attach it to your antenna.
Try a. If youre looking for work in the Helium ecosystem, check out Helium Jobs. Calculating RF Power Values (explains why a 6 dBi antenna doubles your power), 900 MHz: The Wireless Workhorse. Location is far more important than antenna (or elevation, for that matter). That means that unless you aim your antenna very carefully, you can blast all that power into places that have no hotspots. Id re-ping them on email one more time, and check through your spam for confirmation. 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. or a 4dBi(Bobcat) antenna, and is good enough for most miners that are in well populated areas with lot of miners around. As seen above the RF signal can bend around large structures. Required fields are marked *. Yep, go here. Theres a chance the signal will bounce off something and get to the far side, but thats unreliable. My buddy says to purchase a signal booster which attaches to the Miner (Bobcat 300 in my case) to boost signal ex: FBP-915S. Its Line of Sight that is the secret here. Now, those arent how it *actually* works. saw filters? Beyond 9 the pattern generally gets too precise to provide the Wide coverage (the W in WUPU) that we want. I live in Gillingham dorset in UK at altitude 70m.there are a few hotspots in my town but they all seem to be inactive. Forests are RF sinks.
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. Id wait a few more days to make sure. Its an example of the incredible earning potential that exists when providing asymmetric value to the network. The topic of radio propagation involves a tremendously deep dive all the way down to the fundamentals of physics, but well keep it pretty simple. LoRa can easily do a mile. I am thinking about 6dbi but if 7 or 8dbi will work better then I will go for it. Antenna strength can be simply thought of as the power of the signal the antenna sends out. As you can see, there are 3 main frequencies of antennas in the market and getting the right frequency compatible with your region is vital. Almost always better to get the antenna outside & up high if possible.
Lets start with topography. This is yet another reason not to set up inside. Some of the signals bounce off to the side, proving that RF is weird.. Relax. Smaller gain antennas like 3 dBi or 4 dBi are typically very small antennas for example 300 mm long making them popular also in applications where customers dont wish to install large size antennas in neighbourhoods where they feel may be sensitive.
