My Comcast RF is grounded outside. They grounded it for me last Summer because of some new update/law to the electrical code or something...

Anyways, is it still recommended that I hook the RF into my Surge Suppressor? I am about to re-wire all my RF cables from the Comcast box outside into my home and inside my home. Just purchased new Blue Jeans RF cables and a Monster 2-way splitter. I have heard that if your RF is grounded outside, then it is better to run the cable directly to the TV to minimize loss of signal. Is this true? I will be using the RF for NTSC and QAM signals. The splitter is being used so I can use cable internet off the same line.

Also, not sure if it matters, but I had an electrician put a Surge Suppressor on my new electrical box when we updated our house to 200amp service. Unfortunately I only have a dedicated outlet to my computer room and not to the new home theater room. I just bought a new HDTV (not hooked up yet) and I dont want to risk a surge coming through the RF. I know the electrical outlet will be okay because of surge protection at the main electrical box and also my Tripp Lite strip.

So the bottom line is that I want to protect my home theater via the RF and I want the best possible signal via the RF.

The grounding outside should eliminate all surges. Going through another one inside may introduce more issues (signal degradation).

If it is possible, have your electrician run a dedicated separate circuit to your home theater area. That is a good thing to do.

running the coax and phone line thru a surge suppressor is old school technology left over from the analog days .

If these lines are properly grounded into the home that is fine. just plug the power cords into the suppressor and let the surge unit do its job on the power lines...high low voltage, brown outs, turning on/off the audio equipment in sequence.

The little powerstrips are useless.I used panamax in the old days and switched to big pure AV units in my hometheater rooms at home. I disconnected the spaghetti mess of coax and phone pass thrus years ago. It made a huge pile in the middle of the room...when I reflected back. what a waste of money.
