    use the existing rg-6 QS cable that I'm currently running to my dish & run a diplexer to connect an OTA antenna for local HDTV reception? My father-in-law gave me the clip-on terk antenna for Christmas that attaches to the dish, but it's not strong enough. I live about 25 miles from the antennas, and am thinking about getting the Channel Master 4228, because I live on the other side of a pretty large "mountain". I've been using a radio shack double-bow tie antenna, and have been able to get NBC, CBS, PBS - but the wife doesn't particularly like the cable being run across the floor & out the door. I just ran a separate RG-6 cable in my attic - thinking that if I could receive reception on ground level outside, then it would surely work in my attic. I purchased a LARGE VHF/UHF/FM antenna from Radio Shack to just see if it was possible - didn't get anything. I would much rather use my current cable coming from my dish if AT ALL possible - is it? Any help would be much appreciated. Thanks!!

    Yes, diplexers allow you to run both signals down the same cable, but I understand there is a penalty in picture quality.
    What does that mean, “didn’t get anything?” A big antenna should bring in the stations beautifully, much more so than the Terk or double-bow tie.

    The "bigger than my house" antenna didn't pick up any digital broadcasts within my attic. It was able to pick up some analog, but no digital. The double-bow-tie was able to receive NBC, CBS, PBS in digital via RG-59 run across my living room to the outside. I get a great signal on my dish, I'm just wanting to also mount the OTA antenna to the back of my house in the same general location & direction of the broadcasting antennas. Any help would be much appreciated.

    I’m not sure if digital needs a special antenna or not, but if your bow tie was picking them up I’m guessing not. Even if not, the rooftop should be able to blow away the bow-tie with regular channels, especially the distance you are from the broadcast towers.

    The only reason a bow tie would outperform a “real” antenna would be if the latter isn’t oriented correctly towards the towers (the large antennas are directional), or the cable or transformers feeding the signal is bad. Simple as that.
