[TowerTalk] Lightnig Arrestors at tower base or house entrance?

[Gene Smar]

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!
