[TowerTalk] Polyphaser Questions

[David Calder]

Exactly. Mine are mounded directly on my ground buss bars just before they
enter the shack. I run all hardline
and it's grounded to it's own buss at the bottom of each tower.

Working for one of the larger tower companies here I deal with the cell
carriers everyday and I just copied
their design. I figured if it saved their equipment it was good enough for
mine.

I can only speak for my approach, but I do not use them at the tower. The
coax shield is grounded to the tower at the top and bottom using a bracket
and bulkhead connectors. A slightly more efficient way would be to use a
more streamlined ground for each cable but the bulkhead connectors work and 
are much easier to install.   Then where it enters the house I use run them 
through a bulkhead that is tied into the entire ground system.
