Low Cost Remote Antenna Switch circuits and parts

A solution for those who need an extra coax run is a remote antenna switch. And there are two ways to power a remote antenna switch. You can use a separate control wire from your operating position. Or, you can run the relay control voltage up the center conductor of the coax cable. Putting the control voltage on the coax center conductor is the cleanest way, and in my case, the only way to do it.
