I put up a Channel Master 4228 antenna outside on a rotator. It pulls in all the local digital signals with no dropouts. ( I do have to spin the thing to get KYES and KDMD, but I usually don't go there anyway.) When I bought the antenna (online) I also bought a Channel Master 7777 mast mounted preamp, thinking it might be needed. But I don't need it. In fact, when I had it connected, I couldn't get squat. I think it over amped the tuner.
As an aside, I also am experiencing audio dropouts through GCI. (I have basic cable). If I change the channel, then come back to where I was, the audio feed comes back. Weird.
As another aside, I talked to Jeremy Lansman, President and chief engineer @ KYES. He said that since WB had bought UPN, that the UPN feed would be going away. I asked what they'd be replacing it with. He said possibly WB, depending on the money thing.
