I did a test with my VNA to see if Airbuddy is amplifying the signal in direction from antenna(OUT port) to the miner(IN port). I build an attenuator to bring the signal down to -17db. In the test, this amplifier bring the signal up to -4.2db(from -17db), so this is almost 13db win(for RX)!
I've replaced the original SMA ports from amplifier with RP-SMA to make it plug and play, between miner's port and cable!
The power solution is not ok because the amplifier doesn't fit to the Sensecap M1, so the final solution is not the one presented in this video!
I'm still learning how to work with a VNA, so please understand!(don't know how to test TX way :((((, but i'm learning)
Sorry for the video quality, i'm working to improve this!(better camera)

Thanks for watching!
