I'm confused. I receive HD signals beautifully from DirecTV. I recently bought a Zenith Silver Sensor antenna to pick up OTA HD signals. I live in West Hartford , Connecticut (zip 06107). I am hoping to avoid having to mount an antenna on the house. I am able to pick up several signals (CBS, NBC, PBS, and ABC), but I need to reposition the antenna each time to get each station. Is this normal? Is that simply what I should expect? Or are there antennas that would do a better job of picking up different signals from different directions? The Silver Sensor is passive, so there is no signal gain. I had hoped to put it in my garage attic, but if I have to re-position it everytime I change channels that would be senseless.
