Hi, Dean --
Sure! Andrew makes what they call an 'angle adapter' (p/n 31768A); we
called them beam clamps. Anyway, it's a stainless steel U-shaped bracket
that will bolt on flat tower members and is part of the Andrew ground kit.
The jaws will fit up to a 7/8 inch thick plate. You bolt your ground wire
to it and there you go. The bolt that secures the angle adapter to the plate
member actually digs in through the galvanizing to give you a real nice
mechanical and electrical joint. Tower Tech has them for $7.00.
