Christopher Miles wrote ... If the plexy is the primary form, what i do is weld a disk to base of plexy tube with MDC. A small hole in center of welded disk allows ¼ inch brass bolt coming out of secondary bottom to drop through. There is a brass nut soldered on a copper plate under plexy disk to connect RF ground to. The bolt just threads into the nut so you can remove easy. I can remove a 40 pound 4 foot secondary in 30 seconds without tools at @  this way.  Cheers, ch   
you have a secondary thats only 4 feet but weighs 40 lbs? wow thats sounds kinda heavy for that size.
