I was listening on the 145 a couple years back and these fellers were talking about using a glass jar as an insulator. so that's what I do in the spring to fall months, is unscrew the antenna and put the connector into an empty glass, supposedly that's enough insulation from any badness should lightning hit the antenna on the roof? That's as fancy as it's gotten over here in the shack..
