Topband: Relay switching at the base on antenna

[MR TREVOR DUNNE]

Could you point me in the direction of a circuit for this I'm struggling to visualise it,

Thanks

Sure! I'm doing it with a 24 volt vacuum relay at my antenna. Run 12 volts to
the antenna and through a series diode (for isolation) in the return line to the
transceiver PTT. I have another diode in series with the amp keying circuit to
keep it from affecting the relay at the antenna and vice versa.
