The basic idea is to extend the range and effectiveness behind obstructions of FPV video for my smaller racing quads. I use a tiny 1.3 GHZ transmitter on the quad and then a receiver mounted on a remote tripod. I feed the composite video and audio into a small 200mW 5.8G transmitter with a helical antenna pointed back to where I am. All powered from an XT60 lipo.
- 5.8 helical antenna back to my flying location lets me use standard Fatshark goggles, etc.
- Off the shelf components
- Allows operation on the back side of hills.
- Super tiny low power transmitter on the quad.
- Analog video so virtually zero added latency.
It works great! This was a test last year but I haven’t gone back to 1.3G after a rebuilt that 250X into a 180H frame. It is still an “active” project where I plan on mounting things in a weather resistant box and including a UHF keychain remote control to activate and de activate it.
Blackbox video you can see the repeater and that I can fly behind the sand hill. WIthout the repeater I couldn’t do that.
