Twin Quad Frames X215/SX225 VTX antenna mount

Held at an angle of 46.83° (Actually, I have no idea. Real number is around 45°) that all the professionals suggest (again, have no idea if that is true).
This mount holds your SMA for your VTX at an angle to clear the props and away from the battery if you toilet tank. Tight fitting on standard standoffs to prevent slippage.

This should work on any other frame with a 30mm spacing between the rear standoffs.
