Anyone here flying freestyle on 1.2/1.3GHz analog video?
As an RF engineer I'm surprised that no one is doing that.
I know some people may argue that:
- Antennas are big - but how can you say that while using 900MHz ELRS dipoles, which are bigger?
- They interfere with control links - if you put a notch filter on the VRX and use a good enough VTX and don't blast 1W at 900MHz or 2.4GHz, nothing will happen.
- That's illegal - While it is illegal without a ham radio license, 5.8GHz @ more than ~15mW is also illegal without it.
- It may cause GPS interference - That's true, but with some good RF knowledge you can still make it work properly.
On top of that, 1.2GHz has some serious advantages:
- Superior penetration - lower frequencies go through walls like nothing.
- Superior LoS range - with all omni antennas you get similar range as with 10dBi on 5.8GHz.
- Less congested spectrum.
