I need one for HD OTA reception since my old indoor is iffy these days. I presently am with Dish with 2 HD receivers, the 811 and a 942 both of which I'd like to stick in their individual OTA source. I tried the Terk clip-ons which gave me worse reception than my old rabbit ears. An outdoor one to be mounted with the Dish sat on the roof would be my best bet. There, I can easily combine the sat and OTA cables with a diplexer and split them out to the receivers inside. A medium sized one would be best preferably not bigger than the Sat dish as well as costing below $100.... oh BTW, I'm needing antennas in the "yellow" range.
