    After fooling around with my OTA antenna and realizing how much the OTAHD signal behaved like a satellite signal I was wondering if hooking an amplifier like Radio Shacks outdoor amp would help with rain fade?

    That depends on your antenna; three times nothing is still nothing.

    If you are going to invest in an antenna, I highly recommend that you go for a VHF/UHF model as opposed to a UHF only model. It is likely that many stations currently broadcasting analog in the VHF band will move their digitals down to VHF after the transition to digital.

    I guess I didn't explain myself well. I meant putting an amp on a satellite line before it hits a reciever. Would this work with rain fade or mess up an LNB or something?

    An amp will only help if your cable run is longer that ~150 ft. Rain fade is due to lack of signal at the dish. The only way to over come rain fade is better alignment or a bigger dish.

    Here another way to look at it.

    Say your signal is like a nice 4x6 photo of your favorite girl. But then something happens and half the picture is torn off. If you take that picture over to the copying machine and blow it up by 2 times.... you still have half a picture!


    It’s all about where the signal is collected. THE DISH! :eek2:

    Scott is right. Garbage in = garbage out. An inline amplifier will boost the existing signal to push it through a longer run but it cannot amplify a signal which isn't there. When the signal from the dish is gone, it's gone.

    I had that radio shack amp hooked up to my line coming from my outdoor antenna on the roof back when my line had water in it and corroded. When my line was corroded it did help the signal. After I redid the whole line and put that amp on there again it over amped the signal and no stations. The amp may pull in some weak stations but when your watching stations that have a good signal it will over amp them and you wont get anything. If you having problem with getting locals get a larger outdoor antenna. ;)
