    Good morning guys!

    Thanks lrhorer, there is great info here.

    Stopped by Lowe's on the way home and grabbed a 5/8" x 8' copper coated ground rod. Came out 10" from the house to avoid the footer and placed the rod below the cable box. Drove it down until there was 9" left above the ground. It was dark and raining, so I called it a night. Will work on grounding the cable this evening. Going to have to run a new cable, I assume keep it a solid strand and short as possible?

    Grabbed this clamp at lowes.


    Fits the rod just fine, but will have to mess with it some to get a tight fight on the ground wire. I had some eyelets to fit over the set bolt but they weren't tight with the bolt run up. It looks like this clamp is made to add something a little thicker to your 5/8" rod.

    Thanks Les. I'll look into the isolator. I may check with the guys at the city cable department. We have a Radio Shack here but I'm not seeing anything online for a video ground loop isolator.

    You're welcome.

    Electrically, that would probably be OK, but you really probably do not want a copper-clad steel rod sticking up in your yard. It presents a tripping and minor impalement hazard, especially if the grass gets tall or at night, and presents issues when mowing the lawn. Unless the rod is blocked off by some yard appurtenance, I would dig down a bit (8 or 10cm), drive the rod all the way down below ground level, attach the bolt, and cover it up with soil.

    Well, not necessarily. Proper routing that eliminates issues such as tripping over the wire or accidentally cutting it are of greater concern. Don't run it half-way down the block and back, but otherwise, a few feet more or less shoud not make much difference. I would definitely bury it a few cm down on the run between the house and the ground rod.

    Yep. That's the one for a 5/8" rod. They also make "spider" clamps, but they are usually used with 3/8" rods.

    You shouldn't. The little bulge at the pointy end opposite the bolt is designed to hold the ground wire. If the ground wire slips out of that channel with the bolt tightened, then you are using wire that is a little too thin. #8 or #10 wire should work, or maybe even #12.

    We are both "Les", actually. He is Les D. and I am Les R.
