Yes, I am using a small relay in my E-probe antenna. It connects the whip to ground when power is removed. I did not notice any change in sensitivity after adding the relay (although I did not measure it). The relay adds only a pF or so which is quite small compared to the whip//FET capacitance in my antenna.
