Query: Good Antenna

I live 35+ miles from towers, most of which are roughly the same direction - within 15 degrees. Installation was easy - as high as I could get it on outside of house. Amplifier has a tiny switch - make sure you don't miss it. I pick up about 25 extra channels, but many are useless...weak signal, foreign language, religous, and duplicate channels. There's also channels that Dish doesn't know about so they show up in the program guide without any programming info. About 12 are worthwhile and 6 or 7 of those are HD. This includes "blue" signals. I was surprised that some channels are coming from nearly opposite direction - must be reflected. Once in a while, especially in windy weather, my signal strength goes down on all over-the-air channels and occasionally I lose the signal all together - a bit irritating. This is the first and only antenna I've tried so I can't compare to others, but overall, I'm very pleased.
