I use cheap RC transmitters and receivers to control practical effects for video projects. I buy the really cheap ones. You usually get 2 in a pack. One 40mhz and one 27mhz. I'd like to combine the controllers in a single box for convenience and so I can use better quality switches. I have one in there now and it works great. But, rather than have 2 antennas sticking out of the top, can't I just use one and connect both transmitters to it?
I'd never need to be pushing buttons on both at the same time, so there would be no need to use a diplexer. I'm aware that antennas are supposed to be a certain length in relation to the wavelength of the signal or some such...thing is, while ONE is FAIRLY close to what would be needed for a 16th wave antenna, the other is nowhere near. In fact, I think they are all about the same length. In that case, is it okay to use one antenna? Or would all the other junk from the controller not being used at that moment also being attached to the antenna in use cause a problem? It's no problem to have 2 antennas, I just don't see why if it's not necessary here.
Why ARE they all the same length when half are 27mhz and half are 40?
