Dont just look at the gain of an antenna and think higher is better. would that matter around hills?so can 6.5dbi reach higher over the hill then 8.5dbi?Am i understanding right? This is just in case the antenna gets hit with lightning and deals with static buildup. For this, we need an external pole-mounted helium miner in an external weatherproof case. The only thing you can do, is ensure you're giving your TX signal the best possible chance of reaching those remote devices. This provides dangerous static build-up to safely discharge to the ground. While it seems that a high gain antenna will get you better range, it doesnt really matter. That'll probably get you 80% of the results you could get with far more effort and expertise. as this number is variable based on the current $USD/HNT price as defined by the HNT Price Oracle.). 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. Thanks to Implicit Burn, if you have enough HNT in your wallet to pay the transaction fee, the Remember that roof tiles will reduce the radio signal as well as every tree and tall building in the path of your antenna beam.
