I have a ‘Hubsan H501S’ drone, a Fatshark Dominator 3, and Laforge Diversity receiver modules. The ‘Hubsan H501S’ is a great slow flyer and trainer. It also comes with an FPV screen on its transmitter, but it is small and unusable.
As mentioned above, I have Fatshark Goggle with diversity receivers. I also understand antenna FPV design. I assume the 5.8gnz fpv transmitter antenna is an omni-directional one, inside this small fuselage. My question is regarding the best choice of diversity antennas because the transmitter antenna inside the drone is obviously not circular polarized and its location and direction is unknown.
My choices are:
- One circular polarized quality fpv antenna and one omni-directional 3db ducky.
- One circular polarized quality fpv antenna and one 14db (16") ducky.
- One RH circular polarized quality fpv antenna and one LH polarized quality fpv antenna.
- Or any other combination of 2 antennas.
Your thoughts?
