Ground kits at top and bottom of vertical feedline run (before any bends),
and another ground kit at the entrance port to the buildling/shelter.
Polyphasers inside the shelter mounted to the the common-point ground bus
bar for all of the indoor equipment, with the indoor common-point ground
tied into the site ground system using low L/C conductors (3" Cu strap
preferred, #2 AWG for short runs, avoiding right-angle bends).
