I don't know, 25 feet seems pretty doable if you have a couple of pushup
poles. I have a 33 foot MFJ push up and a tripod to hold it. I know
Len has one. I've also got a drive on mount that I made myself with
easily acquired plumbing parts that could be erected, and guyed into
place...in theory anyway, I've never driven off of it. I'd be happy to
set some time aside some Saturday morning to come up to Winona and play
radio with some of you.
