Repeat after me -- LIGHTNING IS NOT A DC EVENT, IT IS AN RF EVENT. Write it 100 times on the blackboard! :) That choke only discharges DC. 73, Jim K9YC made that comment. floating.. and not grnded [l

when a lightning storm is nearby and ya hear that ever rising whine in the rcvr that finally culminates in a crack.,,,, something is obviously building up on something, before the discharge. Exactly

At the frequencies where we use them, they have a high resistive impedance. At the lower frequencies where lightning dominates, they look like a lossy inductance. That's exactly what I am measuring,

the ONLY function of a lightning arrester is to equalize the voltage between conductors. It clamps the voltage between conductors to some low value that is designed to prevent damage to other compone

And there's another subtle problem that crops up with these gas tube or fast diode type suppressors (anything that breaks down and has a very low impedance after breakdown).. And that's the fact that
