Thanks for the info. Do you have a link to a TV Fool signal analysis you can post?

I'm familiar with the Los Angeles area. If you are blocked by mountains, then you are probably better off with an Antennas Direct 91XG for UHF and a Winegard YA-1713 for high-VHF (KABC, KCAL, KTTV, and KCOP).

The 91XG mounting bracket allows for the antenna to pointed nose-up toward the ridge line. This puts the heart of the antenna pattern up where the signal is really emanating from.

The high-VHF antenna usually does not need to be tilted because 1) VHF signals can diffract over mountains better, and 2) the vertical beam pattern of these Yagis is very tall so you wouldn't notice much of a change anyway.

The two antennas should be combined through a Pico Macom UVSJ to prevent any mutual interference between them.
