I know antenna grounding has been asked a lot of times but I can’t quite find the answer to my question so here it is.
Can I ground the antenna (coax and mast) to the main electrical service panel outside of my house? I am talking about making a connection to the outside of the box with those grounding screws and wires, not the inside of the electrical box.
This is how Comcast grounds their coax using a ground block, and how the phone company grounds their wires. Both are grounded to the service panel with screws on the panel’s hinges. I am just wondering if it’s safe to ground my antenna this way too.
My antenna and electrical box are all in the back of the house, but the ground rod is in the front of the house. So it’s pretty difficult to ground my antenna to the rod directly. The antenna sits directly on the ground (a concrete sidewalk next to the house), not on the roof.
I feel the setup is OK for removing static electricity from the antenna, but may not be good for lightening. Although chances of this happening here is very very low (never seen one near by in 20+ years), I’d rather be safe than sorry.
A related question, are there any grounding of the mast by having it sitting directly on the ground? (again, concrete, not soil). Lightening is usually associated with rain, so when it does happen, the ground will likely be very wet, won’t the wet concrete just act as a ground path directly?
Another idea I have is to ground the antenna directly to the #6 ground wire in the craw space between the service panel and the grounding rod. But I am not sure if it’s any different from what I have now.
The alternative is to install a new ground rod next to the mast (drive it through the concrete), and connect the new ground rod to the main electrical panel. But that is a lot of work and since I have to pay someone to do it, it might be cheaper to just run a #6 from the back of the house to the ground rod in the front…
