Not so good reception with CM 4228 - SF Bay Area

[kaydee]

Based on intelligent recommendations all around, I installed the CM 4228 on my chimney (San Jose, zip 95117). Most of the broadcasters are 41 miles away at 305' from my house. I oriented the antenna using a compass, as best as I could and pointed it in the direction of 305'. The antenna is installed at about 10' on top of the chimney and there are no obstructions around the area. I connected the antenna to a Philips HDTV with a tuner.

I notice that I can receive Ch7 (KGO), Ch9 (KQED) and Ch11 (KNTV). The reception is not the best but it isn't bad either.

However, I just can't receive CH5 (KPIX - CBS)) or CH2 (KTVU - Fox). Both of these stations are at the same orientation as the rest and also at the same distance.

What could be going wrong here? Should I consider some other antenna? Or an amplifier?

Thanks

Amplifier, like CM Titan 7777 (?) will help.
It helps me to get Chicago OTA from 72 miles and antenna in the attic.

Point ant for best signal, not with compass.

Are these all digital stations or are some still analog? If analog, the antenna will not pick them up as it is a UHF only antenna. As previously mentioned, aim the antenna for best reception not by compass. I use the same antenna and am 50 miles from the local transmitters and I get exceptional reception. Also make sure that your cable and connectors are in good shape and tight.
