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.
