Hi,
I am installing a small antenna for an HDTV and I want to be sure it is adequately grounded. My understanding is that it needs to be grounded to both a separate rod and to the main service ground; my main issues have to do with logistics and equipment.
First, the rod. At the hardware store, I was told that copper plumbing pipe is sufficient, but I'd like to be sure. I was only able to get a 3/4" pipe 4' into the ground - I realize that by NEC standards that is not sufficient, but will it do in practice? Whatever rod I use, grounding the antenna mast and the cable grounding block to it seem pretty clear.
Grounding the assembly to the main service ground is where I'm not clear. My understanding is that I should run a ground wire from the rod to the main service ground. The antenna and the service box are on opposite ends of the house, and the house is attached on both sides, so I cannot run this wire around the outside of the house. Is it safe to run it into the house and through the basement? What type of wire do I use, and does it need to be covered? If I am to attach it to the main service entry box, does it have to run into the box?
Thanks for your patience; I'm new to this.
