Thank you, TV Fool, for educating me about OTA reception. Yesterday, Custom Antenna Service (info@customantenna.com), apparently the last legitimate installer here in San Diego, added 10' to my mast, installed a WIN-AP8700 pre-amp and RCA-VH126W rotator to my existing Winegard HD7697 directional antenna. Am now receiving LA 4, 7, 11, 13, 22, 30, 58, and 63, as well as San Diego/Tijuana/Tecate. Still no KCBS-2, KTLA-5 nor KCAL-9 (since FCC, in its wisdom, assigned 9.1 to KSDX-TV which shows on TV Fool signal analysis as analog channel 9, but registers on my receiver as digital 9.1, same as KCAL).
Have yet to explore full range of rotator.
Again, thanks for your insights, Electron, et al.
