This is the antenna that wraps around the dish. It "works" if your close in, line of site to towers where the local channel signals come from, the dish is pointing towards the towers and your not fussy about quality of picture. They're a cut above rabbit ears because you're outside the home, but that's all. It has a built in pre-amplifier that runs off the power from the satellite receiver. This may cause you problems if your very close in by over amplification. Also, if you're thinking of using it for the UHF antenna required for HDTV, you may have noise problems from the combination of dirty DC power on downlead, as well as harmonics from the satellite frequencies. TV signals are transmitted in a horizontal plane. This antenna is curved. It will work, but has limitations. Directionality, which is what helps eliminate ghosting, is lousy. Terk also makes other models that look like a 4ft long 1X3 board, works better, but still has limitations. The best type is still the old fashioned outdoor type mounted up and away from trees, chimneys, roofs, etc. Doesn't have to be big, or high, if area doesn't need it. Yes, there are lots of people who put them in attics and in the house and they do "work". But, there is usually some ghosting, and each location is unique in how well it really does. What looks great to some in reception quality may be lousy to others.
Bottom line, if you want to try it, be sure to get a money back guarantee or good return policy if it's not sufficient.
Sorry for the long post, but I replace these for unhappy people, don't want you to be.
