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.
