Quoting N4ZR <n4zr@comcast.net>:
I'm wiring up a relay to be used to open the feedpoint of my 160M
inverted L. My intention is to have it connect the feedpoint to the
transmitter when the relay is activated by PTT and open the circuit
on receive. I will be running 1500 watts.
My question is this how heavy does the wire need to be between the
antenna side of my common mode choke and the relay, or between the
relay and the feedpoint? The relay is rated at 16 amperes
continuous, 30 amps switching. I've been told that current rather
than voltage is the issue at the base of a quarter-wave. My normal
instinct would be to use something like No.12 or 14 wire, but the
terminals on the relay are roughly the diameter of #18 wire, and the
center conductor of the common mode choke (wound with RG-400) is
similarly small, so would the heavy wire be overkill?
