Larry:
I came up with a way to homebrew a coax ground clamp for the RG-213 coax
runs down my tower:
http://lists.contesting.com/archives//html/Towertalk/2002-07/msg00698.html .
The trick is to really waterproof the ground clamp area on the coax with
adequate tape or other sealant. I can send you a couple of photos if you're
really interested.

Could someone please explain how you can ground a coax shield, on a
continuous run down a tower, without letting moisture and humidity get
into it? Thanks!
