Re: Air as an insulator ...
As Milt said – with lightning, all bets are off …
From: http://www.aharfield.co.uk/lightning-protection-services/about-lightning
There is estimated to be around 2,000 lightning storm active around the global at one time creating over 100 strikes per second. These thunderstorms generate a potential difference of 200,000 to 500,000 volts between the Earth’s surface and the ionosphere, with a fair weather current of about 2×10-12 amperes/meter2.

Jerry, What you saw happened one time...in your basement and could never be recreated...anywhere else...at any time...and you’re dealing with huge, massive voltage, and there are no constants. Air is the best insulator there is. Put a lot of air between the voltage terminus and ground and see. Is 6’ a lot? Apparently not when you consider the unknown and unmeasured voltage of lightening. Concrete is also an insulator. Not a very good insulator, but none the less it insulates to a point. Google “Ufer Ground” and see how concrete is used in construction for grounding...and I mean HUGE buildings! Milt. N6MG

I seriously doubt this theory. Where I once lived just outside Chicago, Had an 4BTV with radials mounted on roof of house. Spring storms came around and I ran to basement to disconnect antenna while lightning was all around. After antenna was disconnected and coax was hanging 6 feet above basement floor, I watched a big, blue arc go from coax to basement floor.
Doubt that air is a good insulator.

Everyone needs a SnS (short n sweet) macro set. What I find funny is when I do get dx, and they send me a brag file. Or later on a flirty email. Common sense really isn't so common it seems.

You are perfectly making my point spot on… If air is such a great insulator, what will prevent the lightening from jumping a 1” gap of a glass fuse?

Re: Air as an insulator ...
Had a couple of Pyrex insulators rated at something like 5 KW and were about 8 inches long. Unfortunately, they disappeared from my parents garage many years ago. The 2 little thieves hit every garage in town and only stole radio stuff. They're probably dead or still in jail... Oh yeah, they worked at Knight Kit when I was there back in 60's ...shipping dept. and had been putting labels on stuff to send to their friends/fences. They both got fired ! Jerry N9AVY

Took a while to get him. Lots of ops calling when he's in QSO and sending long macros. Lots sending their calls several times. A bit of a zoo ! Seems like a few inexperienced operators. Once he acknowledged me I sent "599 IL TU" and did Admiral Halsey's famous naval maneuver . Jerry N9AVY

PSKMeter--> one more time + loss's
Joe, You’re definitely included! At 1.5 watts, you can’t afford to lose a DB or even a fraction of a DB. My #1 DX Elmer, Vince, W5KC, (sk) who lived way back up in Bayou Lafourche`, Louisiana, used to say, all the time: “Prêter attention à la perte's!” In Cajun French that means, “Pay attention to the loss’s!” Have you ever measured your RF output at the feed point of your antenna? It would be interesting to see your output at the feed point of your antenna and your estimated ERP. Milt. N6mg 070-650 LONP #76
PS: Pls do a log search? Have we ever worked? As N6MG? W6QE? Or my club call, W6QP?

I have been anxiously watching the past couple days. I am glad to report back that you definitely appear to still be alive. I was worried we were being contacted from the other side on a freq that we were not aware of. This could have got you in the record books. TIC Barry ---In 070@..., <n9avy@...> wrote : While remote operation seems great, I would be more worried about the occasional lightning storms taking out antennas, radios and the computer. I've had some nasty nearby lightning strikes in the past and when I lived several years ago, I had an 80 ft. tower which took a couple hits. I realize insurance might cover this, but after a few hits the insurance company might start questioning claims... Jerry N9AVY
