[TowerTalk] grounding

[Rob Atkinson, K5UJ]

okay Gary, i'm going to be the stupid one and say that there seems to be 
contradictions in what you advise.

let's say i have my service entrance, its ground rod and panels, on one end 
of the basement.   the feedline bulkhead is on the other side  of the 
basement.  it sounds like you are advising that i run a shack service 
circuit across the basement  and ground it to the feedline bulkhead which is 
bonded to the shack cabinets and a rod or rods outside.   The circuit, 60A 
let's say,  would branch out to outlet boxes.   this does not sound like a 
SPG in the conventional sense I've been led understand.   it might be okay 
with a large copper strap below grade outside connecting the service panel 
ground rod and running all the way around to the feed bulkhead rod.  
otherwise it sounds like a double point ground.  i have always been told 
that you MUST have everything--satellite, cable, tv antennas, phone, AC 
service, antenna feedlines, and in-laws coming in at the exact same grounded 
location so everything will be colocated and rise to the same potential.   
tnx for ur patience

Hi Rob,

Run it anywhere that you have access. It doesn't need to be outside.
The point is that you do your grounding and power protection at the entrance 
panel for your antennas. The cable entrance panel is your single point 
ground. You have no other path to your equipment but through that panel.
Now an extensive ground system hooked to that panel would be ideal.
