I just put a new stock receiver in my phantom vision. I mounted a SMA adapter on it so that I could try different antennas out. The stock antenna is just a wire with an inner and outer layer. Has anyone tested the continuity between these 2 layers? If I put my meter on the wire that sticks from the antenna tip (the inner layer), and I test for continuity with the jack (outer layer) at the pcb, I show continuity. Is this normal?
