I wonder if there's somebody who can explain a few things to me about RC Rx antennas. In particular, how most Rx antennas are 1/4 wavelength, while at least one outfit sells you 1/8 wavelength.
Loading? Ok for Tx's. You must optimise the Tx / antenna / freespace interfaces, and you have the space to do it.
But Rx's? A chip? What's it do?[
Last time I heard it was "e dot dL" volts to the input circuit. Wrong?
Amplifiers, yes, OK, but make sure the noise figure's low enough so as not to deliver you lots of amplified noise too!
Anybody want to talk this sort of stuff?

Cheers
