Yikes. I'm so embarrassed.
Thank you for your reply.
I just assumed that was the ground wire since all the phone and cable TV and water come into the house from that general area. Then I see this funny looking copper wire sticking out of the dirt, so I assume they are grounding something or maybe there was a rod there somewhere. OOPS.
If I open up the phone box I can see their 10 gauge green wire (I don't have ATT home phone service anymore; don't care). If I open up the little TV cable box (where Comcast Cable comes in) I can also see their green ground wire too. I just don't know (can't see) where that green wire goes to at the other ends. It runs in the internal wall of the garage.
I really don't want to put the Wineguard antenna in the same spot as the DISH/satellite (kinda low; that's where you see the two coax running down along the outside wall). We gave up on them years ago; just never took it down. But that's where the technician hooked up everything when they were here. We want to put the TV antenna higher up on the roof in a different/better location, then have the feed go to grounding block, then enters the attic down to a wiring closet to the amp and 8-way splitter.
I recently re-wired the whole house with CAT6 and RG6, so all the rooms upstairs and downstairs can have a TV and are hard-wired for internet. (When the house was built, it only gave us TV hookup in two rooms, LOL!) Anyway, all my cables meet in the closet of a spare room, second level (my wiring closet) where the Motorola surfboard modem, Asus router, Cisco small business switch, TrendNet patch panel, Electroline amp and Leviton 8-way TV splitter sit. And all my wiring/cabling test passed, according to my test meter.
One of my last steps is to put the TV antenna outside, but I just don't know where to ground the antenna mast and the grounding block before it enters the house/attic.
It can't be this hard, can it?
Sorry for being a noobie and the long post
