Why would you want to try to pump video over VHF? You have line of sight to everyone when you are in an airplane. Use a higher frequency band that allows for much more bandwidth and therefore higher data speeds. The little 1.2GHz video transmitters can easily reach 10km. That is cruising altitude for a commercial airliner. Having the proper license would get you even greater distance with a higher transmit power. Have the drone/UAV transmit ADS-B data and use GPS position to point a high-gain directional antenna at it, that should get you even more bandwidth.
- kawfey 7y agoThis, to me, is why this request is so unusual. This is much more suited for spread spectrum, secure, short wavelength (smaller antennas) and the like, and its surprising that Thales - a world renowned avionics corporation - is behind the push. It's also why I think this big 2m band scare is moot; someone didn't actually do the engineering, it's like they just threw out a random number and put it in a powerpoint slide.
