[TowerTalk] Grounding

[James C. Hall, M.D.]

Hi Dwight:

I have a similar setup with the tower 150 feet away from SPG, connected by
4" PVC. I use #8 solid copper wire for ground screen at the tower and
connect to the SPG (outside the pipe) with the same wire, via the ground rod
at the base of the SPG. I use copper flashing from this ground rod to the
next ground rods (16' separation) to then tie to the service panel ground.

TT:

Here's the situation.  I have a tower that is 130 feet from entrance to my
shack and it is connected with a 3 inch plastic pipe. I am running 2 LMR-600
coax, rotor control, and 2 antenna switches on the tower.  Should I run a #4
bare copper ground wire inside the pipe from the tower to the SPG at the
entrance to the shack; run the copper wire along side of the pipe or just
ignore the #4 connecting the two together?  

 

Further, the tower legs are grounded with 3 inch copper strap at about 25-30
degree angle from the tower to 8 feet copper ground rods about 8 inches
below grade and the rods are connected with 3 inch copper strap.

 

Lightning is my main concern.  Advice from all you wise sages please.

 

Dwight
