I live in Whittier, which is about 27 miles from the broadcast source (Mt. Wilson).
Here is my setup:
Chimney mounted Winegard Yagi 39 element UHF only antenna plus a Winegard AP-4700 19 db UHF only pre-amp (2.9 db noise). 50' total cabling to the TV. No splitting from antenna to the TV (except for the pre-amp). Connected to a newer smart TV.
I get most local stations with the azimuth set to 359 degrees. I do not get Fox (11.1 @ 355 degrees) and local station KCAL (9.1 @ 354 degrees). Even when I rotate the antenna to 355 or other close azimuths. According to antenna.org, this is my only broadcast source. I placed a slight tilt to the antenna shaft to possibly improve my l.o.s. over the hills. I believe that the elevation to the top of my antenna is 389'. Mt. Wilson is 5710' elevation (at the mount top, not to the top of the broadcast antennas?). I calculated that the tilt should be about 2 degrees up. I believe that this tilt beams over the hills, but I cannot be sure.
I tried a different yard location with the antenna at 20' higher, but the results were similar.
Here are my obstructions:
(1) A large evergreen conifer tree which blocks line of sight between 315 to 355 degrees.
(2) Local hills about .6 miles away. Blocks. l.o.s. from about 340 to +20 degrees. These hills have no significant trees on the top of them, only low grasses.
Any suggestions to also get these 2 stations, without losing the others?
I found a rotating type antenna on tvantennasale.com that has a 150 mile range and 36 db gain. It has an integral amplifier. Model LAVA HD-2605. Are these realistic claims? Will this achieve my goal?
