Well, I tried the flat one with no success. No matter where how high I placed it, I couldn't get a consistent signal on two of the channels. So I went to WalMart and got the rabbit ear loop style from RCA. It works great except when I put it where I want it, which is behind the TV. There's just too much interfering for it to work there. Where my TV is in the den I don't have access to placing anything in a window. My only other option is putting it on a closet shelf but that would require running cable along the baseboard which might be my only option. Unless there is maybe a small something that can sit on the glass shelf of my entertainment center that doesn't have the extendable ears. I really though being so close to the towers, I would be able to put it wherever I wanted without problem.
