best antenna for bobcat miner 300

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. Im in France, it work on other frequency and Im a bit confused about the best setup to choose in my case, Remember, its more a factor of how high you get your antenna and how much line of sight it has to other antennas than it is which antenna you buy. 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. Our sales team are ready to assist you, get in touch with us today and we'll help you find what you're looking for! American based hotspots start off by pushing out 27 dBm. Thank you for your response. Thank you and welcome :). Antenna: Stock, Cables: N/A. I would probably put it on 10 meters (+- 1-2 meters). Switching antennas typically doesnt do a ton to change things; location & elevation are what really matter. Many of you will have been scouring ham radio sites to figure out how to improve the range of your antenna. second issue is placement of hotspot.

In this article, McGill Microwave Systems will provide a guide to help you choose the best antenna for your hotspot location. Since changing from our Omni-Directional antenna in this location, it contributed to an increase in the rewards by around 30%. How much power will you lose? Behind me It is suburb area with 1/2 houses everywhere and in front of me it is pretty much wooded area. The concept is simple. In the back of the building it is enclosed space with other buildings Even though a hotspot may seem very close to you, if theres a hill between the two of you, you probably wont witness each other. I wouldnt worry about it, but only testing will tell. Final antenna optimisation could only be achieved by experimenting with different antennas. McGill Microwave Systems are a team of highly experienced RF engineers with a combined experience of over 60 years.

Press the space key then arrow keys to make a selection. Thank you so much for your hard work and support to the community, Im looking for the SenseCAP M1 hotspot EU868

For every increase of 3 dBm, there is twice as much power output. Ok, ok, ok, why does it matter whether or not you know your EIRP? The general takeaway for us Helium Hotspot owners is this: Our antennas wont blast through much more than 2 buildings. Antenna: RFMAX | ROSA-900-SNF, Cables: 5 LMR240, Interesting Pearl Starling Elevation: 35 above ground, Area: North Shore, MA. First: Hotspot placement optimization is FAR more important than what antenna you use, more on that here. hi. Ok, weve got one more thing to consider before wrapping up. You can go to this. 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. Helium Explorer is a great tool to determine the location. Can't find an item on our website? I mean, not for the hotspot owner, but its a neat demonstration of the concept. My first thought is overkill and signal loose out of the gate. Hi Gerogi, click this link to go to the McGill 6 dBi, which should be fine for you. Doing exactly what a ham operator does may give you the results they want, not what you want. So it would be smart to get a ligthning arrestor and attach it to your antenna. However, the use of higher gain antennas will increase the range of the hotspot witnessing, albeit perhaps at the cost of overshooting closer in hotspots with classical higher gain antennas manufactured by other suppliers. Hey Nik, great job with the information above. An interior plaster wall will reduce power by anywhere from .8 to 3 dB. Lets analyse the below Directional Antenna and its placement, Good Location Better Antenna Choice McGill Microwave 13dBi Directional Panel Antenna. I am thinking about 6dbi but if 7 or 8dbi will work better then I will go for it. Hi Nik- I bought the Peoples Antenna based off your recommendation above. Ill round this out with what to definitely NOT do. Anything in particular? 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. So don't go around buying antennas without considering the location well. Earth = No Radio Waves Getting Through. Im sorry rural Florida, youve just got a tough row to hoe on that one.

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. the building is located around a circle place with other buildings around the circle and some trees The best place for an antenna is up high, the best place for the miner is usually somewhere in a temp range humans can tolerate. Best of luck with your placement and earnings, Im stoked to be a part of this amazing community! whats the best one ? Now these signals are not the best in reliability, but they can be a huge help to reach HotSpots that are not in direct line-of-sight. No antenna will blast through hills. Antenna: RAK 5.8 dbi, Cables: RAK pigtail interface converter bundled with antenna. 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. The device has the following functionality. That brings us in a roundabout way to Lines of Sight. While it looks huge and cool and rad, it is the wrong antenna to use for these deployments. Beyond 9 the pattern generally gets too precise to provide the Wide coverage (the W in WUPU) that we want. Imagine your antenna is a torch, emitting light from it. Id run the 5m of cable to keep the antenna high and the miner out of the heat. Let em breathe! So the take away is more powerful doesn't always mean the best in RF world; It's all about how to provide the best coverage in the terrain you are in. Its Line of Sight that is the secret here. The execution can be complicated. 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! 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. Also there is already 2 hotspot already visible on the map around about 150 meters (500 feet) away each. 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). Currently, What happens if you dont update your aftermarket antenna specs on the Helium app? And DBP earns like crazy. In a terrain like this a 2dBi antenna with a spherical coverage would be not suitable, given the other miners are few and further apart. The Glamos Walker is specifically designed for Helium and can be used to Instantly establish what is the Best Helium Antenna to use for a given location as well as providing a host of other valuable information and diagnostic capability when connected to the system APP. If you have to go more than 40, use LMR600 if youre feeling extravagant. regards. Try a. Antennas dont really matter. Run 40 or less of LMR400 cable to it from your hotspot. Hi Martin, The radiated power is delivered much like a sprinkler mounted on a garden hose mounted vertically resulting in a fairly even power distribution, albeit in a much smaller area of up to 10-15 KMs. Provides the ability to send a beacon from any location and record the amount of witnesses for a given potential hotspot antenna location. It's always better to reduce the number of barriers between your antenna and the other miners outside. 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. Heres another I definitely didnt go to art school drawing to demonstrate the idea of runway and diffraction. Establish what the best location is for a hotspot. If you want to run your EIRP numbers, heres how. Its an example of the incredible earning potential that exists when providing asymmetric value to the network. Remember, youll earn the most by delivering the most valuable & provable coverage to the network. Id wait a few more days to make sure.

The 6 dBi should be fine. Theyll all work well. Docile Bone Pony Elevation: 16 stories, Area: Greater Boston, MA. That brings us to ELEVATION. Ive closed submissions on this page. Rock on! 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. How much will buildings block or reduce the power of radio propagation? Id re-ping them on email one more time, and check through your spam for confirmation. I live in Michigan.

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. Then once you pick a winner update the specs on the Helium app? You can get one from Amazon or rak. Will it affect the performance on the antenna if the info is not updated correctly to reflect proper DBis? Location is far more important than antenna (or elevation, for that matter). If you want help with getting the maximum value out of your placements or strategy, Im available for hire. 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?

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. Theres a chance the signal will bounce off something and get to the far side, but thats unreliable. 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? It *routinely* gets witnesses over 200km away. Hopefully the above article has given a basic overview to Antenna selection which the reader finds helpful. This is the location of the HotSpot. Ill 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. The difference between a 3 dBi antenna (what most hotspots ship with) and an aftermarket 9 dBi antenna is a factor of 4! No RF Filters, no Amplifiers are used here. Your house walls, window glass and even house trees falls under the category of barriers. would that matter around hills?so can 6.5dbi reach higher over the hill then 8.5dbi?Am i understanding right? Please only purchase your Bobcatminer from WWW.BOBCATMINER.COM to avoid being scammed. Still, you can see why in *most* cases, you want a low or medium gain antenna up high. 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. Antenna strength can be simply thought of as the power of the signal the antenna sends out. At some distance theyre so spread out that youre basically not going to make a connection, so the effective window shrinks back down. Hi Nik.I hope you can help with this. Required fields are marked *. Cities in general do not have a flat topography, even if theyre built on flat land. The results are a little skewed because of that. what would be the best? Cables: RAK pigtail cable, Sticky Pear Dolphin Elevation: 311 above ground (mountain). Finally, dont worry too much about your antenna. The coverage that Helium network can offer, would be a game changer for the adaptation of the IoT devices more into the everyday life. helium rak dbi antenna lmr hstreet
