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?).

Is a 50 Ohm termination a special value for static discharge? Is it better
than a short or a 10K resistor? The permanently connected 10K would make it
unnecessary for you to screw on your 50 Ohm termination.
