Query: Did not work for us

This product arrived very fast, but did not work for us. We are about 40 miles away from the Washington DC area. Perhaps it had to do with interference between us and the broadcast stations, but a cheap, old antenna did a much better job -- so we switched back. Also, the product arrived with evidence inside that it had been opened and perhaps installed elsewhere before we received it. It was missing one connector plug for the little wings. Nothing looked broken, however.
