Can anyone point me toward a practical circuit for running a few ma at 12 volts
through the relay contacts of an antenna switching system, so as to keep
oxidation from building up? The subject has been discussed from time to time
here but I don't recall any references to an actual circuit. I will have 12
volts available at the relays, but am unsure how to handle isolation of DC and
RF circuitry.
Thanks in advance.
