Scv and JJ, I tried 2 omni's on goggles the other day in the one location standing near my car and flying up and down an old bridge.
I was in the middle and flying to my left and right for around 80 metres each way.
I tried this after watching a JB video which I found interesting.
I tried different antennas and configuration and on my last pack I went back to omni and patch.
All quality antennas and for me, patch and omni still win hands down.
