Warren:

     I made my own coax shield grounding connector and posted something about 
this a few years ago:  
http://lists.contesting.com/archives//html/Towertalk/2002-07/msg00698.html .  
My approach gives you a grounding tab on the coax shield that can be connected 
to the tower by whatever means you choose.  I selected solid tinned copper #2 
wire and compression connector for the coax end and a mechanical clamp for the 
tower's angle steel members.  

     I also grounded all coax runs at the tower top and bottm plus at the SPG 
panel outside the shack.  However, at the shack end I used a barrel connector 
and two PL-259's.  The barrel connectors (from The Wireman) are mounted onto a 
2" x 2" x 12" aluminum angle inside a steel enclosure.  The angle is connected 
to a nearby earth ground rod (< 2 feet away) through an aluminum connector.
