Try the RatShack double-bow tie indoor antenna or the Silver Sensor indoor antenna. Since you didn't mention what (or, whether anything) is in the path, in Long Beach, you might actually have LOS whether YOU can physically see Mt. Wilson or not. Good luck.
For what it's worth, Will, I have the Covina and Kellog hills in my path to Mt. Wilson. Definitely try the RatShack antenna first (catalog # 15-623; $15.99). There've been a lot of favorable reviews on this forum of that antenna, though I personally haven't had any experience with it. I did briefly successfully try the Silver Sensor indoors through two sheet rock walls and a solid core door, but eventually went to an outdoor antenna. (Everytime someone wondered through the dining room, family room, or came to the front door, the picture broke up. The Silver Sensor is extremely directional.) If the RatShack antenna works out, and you decide to keep it, suggestion: get a 300 ohm to 75 ohm impedence matching transformer ("balun") that has insulation piercing twin lead connecting screws at one end and a female coax connector at the opposite end. Cut all but about 6" of the captive twinlead from the RatShack antenna and mount the balun to the remaining attached end. Then use 3' or whatever length you need of 75 ohm coax to connect from the balun to your receiver. This little trick will "immunize" the lead-in against local RF interference.
I do have a rooftop (amplified) and can receive all but one local digital station (CBS). CBS seems to break up a lot more than NBC and KCET. I believe the solution to my problem was answered by all of you. I'll go to Rat's and buy a bowtie an use it as a dedicated CBS receiving antenna.
I'll just have to figure out how to get the two to work in tandem instead of active switching. Any suggestions is greatly appreciated.
