Well I do Dave but I have rather an odd T/R relay arrangement based on
single pole on/off relays which I had available. This means that when Tx
supply is switched off, the antenna is connected to neither transmitter
nor receiver.

I didn't fit a bleed resistor as Andy suggests because I figured it
would have to dissipate a fair bit of power unless it was a high value,
however even a high value will be adequate to discharge any build up of
static, I guess.
