I think you confuse static (not moving) charge with QRN, natural and/or man
made. The drain resistor is not a noise blanker.

I love the idea of a "Static Drain Resistor" in an arrestor if it actually reduces "static" QRN on receive. I've installed about
a dozen ICE/Morgan arrestors on Verticals and Yagi's here in Florida during the past 25 years, where we receive a great deal of "static", but
when doing unscientific A/B tests when listening by ear, I haven't noticed the ICE/Morgan arrestor to be quieter than a Polyphasor. I realize that's
a poor way to judge performance, so I've always wondered if anyone actually measured and confirmed that the "static drain resistor" in the
ICE/Morgan was effective at reducing QRN. Would anyone know of test results confirming the effectiveness of a static drain resistor in an
arrestor? 73, Dick- K9OM
The ICE, now Morgan arrestors work superb. They use a static drain resistor,
then a DC blocking cap, then the shunt inductor, then the GDT.
