I have trammed big 5 el 20 meter Yagis to the top of a 200 footer using the tram system. 2 man crew was required.....XYL to drive the truck and yours truly to be the tower guy. It is a pain to rig it up, and take it down, but I am not a fan of paying lots of money for a crane to drop an antenna....and then put it up after repairs. Bill K4XS
