    Ok, I know you're suppose ground the antenna mast and the coax cable for outside setup. But I have 3 questions:

    1) If you have a full mast that goes in the ground and is supported half way up at the roof eve, do you still need to ground it with a grounding block given it's already planted in the ground?

    2) I have an APC power strip surge protector that all my AV equipment is plugged in to. It addition to power receptacles it includes 3 sets of coax ports - you plug the antenna in one and out through another to the TV. Since I have this surge protector, is it still necessary to ground the coax outside at the antenna with a coax grounding block?

    3) TVs in my house are fed from my ATT Uverse DVR by coax to a box outside with a splitter branching to other TVs in the house. This splitter has a grounding screw (that is currently not used). Do I need to ground this splitter even though the coax is grounded at the antenna (or surge protector; question 2 above)?

    Thanks for your help!

    At the half way up point, I would make sure there's a rubber liner between the mast and the clamp. That way if the mast is hit by lightning, the lightning will go into the ground and not into the house.

    It wouldn't hurt for the same reasons above.

    3) TVs in my house are fed from my ATT Uverse DVR by coax to a box outside with a splitter branching to other TVs in the house. This splitter has a grounding screw (that is currently not used).

    I'd probably leave this one alone and only address it if an issue arises.

    Thanks for your help!
