FrSky X8R/L9R antenna mount

Remixed original thing to get better aerodynamics. The receiver antennas are just simple dipoles inside the cover, so there's no need to rotate them around the antenna axis, just 90 degrees between antennas would be enough for good signal strength.

Added version (v2) optimised for 250 frame with holes for screws on mounting panel and smaller distance between antennas (45mm between cable holes).

This remix also has a version with an angle of 30 degrees for the antennas being mounted.
