Hi.
Forgive me if my question is a "lame" one, but why I can't use the same frequency for those 2 links.
I know a little about radio waves, but Video has one link on one channel. RC control usually uses Frequency-hopping spread spectrum so it uses multiple channels.
I don't know if it will be a good example (since WiFi have a digital signal) but WiFi networks uses the same frequency and there can be multiple of them in the same area.
