Some lightning arrestors use a shunt-inductor from coax center-conductor
to ground followed by a capacitor in series with the center-conductor.
This works in conjunction with a gas-discharge tube:

There is a short explanation of the theory of operation here:

Either a resistor or choke will work to bleed off static, as others have
stated.
But, note that a suitably sized resistor introduces a high RC time
constant,
which in the event of a lightning strike will not bleed fast enough nor
survive the high voltage level to prevent equipment damage. The ultimate
protection is provided by AC coupling the feedline and shunting to ground
with chokes and gas discharge tubes on the antenna side of the coupling
capacitor. See article by Eisenbrey, AB5WG, Electric Radio magazine, #284,
