When I disconnect my antenna, I attach a 50-Ohm terminator to the free
end of the cable for the purpose of continuously discharging the
naturally-ocurring electrostatic charge.

Why not just leave a 10K or so resistor connected full time to the
antenna?

What would be the reason for this? The receiver already has an impedance to
ground (2.2K in my AR8600 MkII), so it wouldn't be needed when connected,
and when disconnected, an inexpensive 50-Ohm terminator with the proper
connector is super easy to connect. Connecting an external resistor as you
suggest would require custom wiring (easy, yes, but why do it if not
necessary?).
