Has anyone done anything along the lines of the subject line using a
mechanical switch/relay arrangement?
I expect that any electronic method would add considerably to the
capacitance from the probe 'antenna' to ground so the best option
would seem to be to use something like the mechanical arrangement in
the old Dow-Key coax relays that had the 'isolated' receive side
contact. This will require a relay of some sort in the E probe that
operates to remove the protective earth only when on receive. I'm
still mulling over the best mechanical arrangement to implement this
scheme-all ideas most welcome.
