Not true! I've spent 13 years as a ham and going on 6 years now at Georgia Tech in Electrical Engineering, and a few years working experience, and while that doesn't make me an expert at all, they still confuse the heck outta me. :) For instance, nobody has yet brought up impedence. I'm not sure what impedence those receivers expect. A project I worked on not too long ago that involved an RF section about the same size as our receivers, expected 300 + j18 ohms I think it was, so something new to me. But regardless of what that figure is, the way we mount our antennas all different ways produces all different impedences seen at the receiver. So I can't see how the system is matched at all. My guess is, it's just not, and there's enough overhead to allow for it. -Charles RCSE-List facilities provided by Model Airplane News.
