Loosing signal at 60 ft distance 150 ft altitude. Modded with argtek which I messed up and ended doing micro surgery to 2.4 ghz remote radio card. Yes my drone has crashed but no major issue. I'm wondering if drone 2.4 antennas have messed up since I measured signal strength with phone Wi-Fi (app) and signal is good. Do I need to go higher in order not to get signal loss on 5.8 & 2.4 feed? Is there a way to measure rf on remote? Either way no rth yet.
