Check out some topographic maps of your area. typical send transaction, where one wallet is sending to one wallet Nik, It may travel further as a signal but the with of the RF signal is very narrow. While it seems that a high gain antenna will get you better range, it doesnt really matter. On this install, I mounted the Helium miner Sensecap m1 in a cupboard just under the attic. Once the size is calculated, we apply a 5000x multiplier. Im in France, it work on other frequency and Im a bit confused about the best setup to choose in my case, Thank you in advance, Lets take a short detour into dBm and power. This is not ideal if you have hotspots all around. The following is a list of the current set of fees required for various transactions, along with Bluetooth pairing mode will turn off after.

We've had a lot of discussion about which antennas are best to upgrade your Hotspot for increased range and even support outdoor setups. The 900 MHz frequency needs some runway, ideally 50/15m to fan out enough to diffract around obstacles. If thats your scenario, get a high gain (6-9 dBi) antenna up over the tops of those trees for maximum coverage. This is what I did the first day I got my Helium Bobcat miner and I only picked up 2 hotspots. 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. FYI stay away from cheap Amazon sellers, my testing has indicated that many of them are dishonest. Anyone using anything less than LMR-400, are shooting themselves in the foot. Its up high with a higher gain antenna, and in general, inaccurately aimed over most of the nearby hotspots. The picture below show some of the most common antenna dBi in the market and their RF coverage. I also use a quality lightning arrestor on the antenna cable.

This in return can earn you a new cryptocurrency called HNT. Calculating the DC cost for Sending HNT . However, the use of 2dBi antenna provides a better coverage. You will lose power in cable run and connection points but this loss in power will not affect the beam angle. Failed Transactions Result in No DCs Being Spent. Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt. All it takes is Antenna, Cable, and some electrical power.
