Do I correctly assume you are running 1/2 inch hardline to the antenna??? 
Else, you are wasting your time!... Line loss will eat any gain you might 
get in the antenna. With hardline, just ground the sheath.

The "radio" will be at antenna site, with a short jumper.  I am powering 
the device with Power Over Ethernet (POE.)  The system will be well 
grounded.  Grounding the shield of the feed line will of course be done, 
but I want to DC ground the radiating element.
