Advertisements Act up as in no longer receiving a couple of my weakest channels. Last fairly heavy storm I lost the channels and trying to aim the antenna to get them back I lost them for good. After another 100 attempts (from the attic to the lower level checking the signal) I finally got one of them back to a lessor degree - the other is a duplicated network although its video is inferior to the one I lost. Bottom line I'm guessing the terrain has changed enough over the years (since the signal has slowly deteriorated) with a line of growing trees most likely to blame. Attic Antenna charges $50 house call and $60 an hour for such services. Not bad at all if he aims and straps it down to ensure it doesn't move from the wind via the attic's air vents.
