Don't know exactly what type of antenna you are using but maybe it was designed primarily for the old VHF frequencies that analog TV used. Most of the digital broadcasts are now on UHF. Unless your antenna is designed to receive UHF freqs, that may be part of your problem. It says UHF/VHF Digital. I am starting to wonder if another antenna is in my future myself. This really does not make any sense to me either. I may try moving it away from the tree first since the canopy is right there. You can get a better performing antenna, but don't rule out your amp. It could be defective and just not doing well at the upper UHF freqs. It have to cover a pretty broad band. |

I had one before and I thought it might be bad so I got a new one. |

Greg, If I were you I'd go to Walmart or Best Buy and buy a cheap, amplified set of rabbit ears and try them before going to the trouble of moving your current antenna around. I think you will be surprised. Should only cost anywhere from $19 to $29 bucks. Just make sure the amp is built into the antenna itself. My brother, who lives 55 miles south of Boston, set up a TV and the set of amplified rabbit ears I gave him in his shed. The antenna is sitting on the shed rafters, about 7 feet high. He gets the three major networks in Boston in HD with no problem along with a few other stations. Was happy because he could go out to the shed to watch the Patriots games. |

I have one, new in the box right here. These houses are not really conducive to RF signals tho. Lots of steel and concrete. Even FM radio is not that great. I was getting a decent UHF signal with one of those wire loops on my guvmint converter out in the tiki bar but nothing in the house. Some of that may have been because the sloped pan roof behind the box was reflecting a lot of signal back or something. I do notice that the TV tuner is a lot better than the RF tuner in a Dish box or even the new TiVo. I also get channel 31 on the TV and 30 on the TiVo. (both the same station as far as I can tell). The TiVo sees the ch 31 signal at 70% or so but it will not tune. The TV doesn't seem to see 30 at all. My portable TV I use to tune the antenna sees 30. |

I had one before and I thought it might be bad so I got a new one. Try removing the amp. I have a homemade bowtie antenna 21ft high and get one of my main stations 50.3 miles away without any problems. Your antenna has plenty of gain, I would remove the amp and make sure the aim is correct, using TV Fool and your address. Mikek |
