    Yes, I did some testing.More testing is needed but conclusion so far is that vertically polarized V is the best. I test vertical dipole, horizontal 110* V and vertical 90* deg V all DIY
    Horizontal V was the worst and yes I mounted TX antenna horizontal for this.
    Vertical V got rid of 2 problems with the dipole. #1 is dipole element snapping of every couple of flights from bending when contacting the ground and #2 is the dipole nulls
    Here is some video to show the problem every throttle cut is a fail safe.There is no video of vertical V because I haven't had a single fail safe yet ( 2 flights) Note this is all within 0.5KM on 433Mhz at 200mw

    Attached is a photo of the installations

    Interesting results! Is the vertical polarized V mounting visible in the left or in the right image you posted?
    However, I think it isn't a good sign if a failsafe happens within 500m with any of these antennas.

    Received mine yesterday and tested the antenna today.
    My old Sander style Monopole is no match to the V at all.
