Why can I pick up all TV stations with my antenna except for ABC?

Episode 928 (2:02:48)

Dave from Corona, CA

Scott has an antenna that has a "rotor" control which will allow him to aim the antenna as he needs. If he doesn't have rotor control, then manually rotating the antenna until he gets a clearer signal will do the trick.

Tim, a truck driver calls in to say that he has a lot of experience picking up stations and he suggests getting a VHF digital antenna, because there are a few in LA that transmit on that band.
