Query: Not worth the trouble

I bought this RCA basic Indoor antennae from Amazon. I live surrounded by brick and concrete buildings so could only pick up 6 - 8 channels and some of them would have lines and digital blocks running through them. When I finally had the antennae pointing in the exact position to get the best reception possible, which was not very good anyway, all it would take was a small bump and I'd lose my reception and all of the work I put into it. I could get ABC, NBC and the PBS stations but never CBS. I had to return it.
