Well, I took the advice I received and went to Schads. I will admit to making the run to Radio Shack, Good Guys, Frys and even OSH first, none of these people know what they are talking about. At least the guy at the Good Guys was honest enough to steer me away from one of the more unpopular antenna brands that they happen to sell.
Anyway, Schads set me up with a Winegard VHF and a channel 12 joiner. I already had two UHF antennas stacked on a mast, so I placed the VHF between them, facing south, towards Loma Prieta. After all of the chatting, driving, spending, working and almost falling off my roof, I still don't get KNTV 11-1 (12). I also noticed while on the roof that the previous installer had installed a Channel Master pre-amp, so I ran ALL signals through this, including the VHF for channel 12 (after the joiner), still no signal. Every other channel I can think of looks great, and has a VERY strong signal, nothing at all from KNTV. When I check it out on my tv, it comes up and tells me the call letters, channel number and program that should be on, there just isn't any signal at all (zero signal registered). I tried pointing the antenna more west, than south, didn't help at all. Any ideas? Let me just say that the guy at Radio Shack on Almaden Expressway tried to get the same channel and could not, he said it wasn't on the air. Can someone in the San Jose/Almaden area verify they are receiving it and tell me what they did to get it?
