Hi, I installed the RCA 751R antenna this weekend and am getting all the channels I wanted. I grounded the coax to the electrical box using the ground installed by the cable company. I just had to change the grounding block to a dual 75 ohm coax grounding box. I also called tech support for the antenna and they said the mast that comes with that antenna doesn't need to be grounded, only the coax. As far as FM goes, I'm not gettind the station I had hoped for. So I'm just going to use the inside antenna I was using. Thanks for all your help. It was appreciated.
