This is a supportless 5.8GHz parabolic reflector antenna for my DJI Phantom 3 transmitter
Initial testing got me way past the old weak signal or loss of signal spot on my range
any kind of foil / foil tape will work, I used Shurtape AF 912 Foil Tape
(I'm still doing range testing and will update this information if necessary)
the reflector wall is thin, (2 passes of the 0.4mm extruder head)
but certainly strong enough for an antenna.
