Nothing is going on at Sutro, you still have issues to work out with your installation.You have a great OTA tuner and installed it as best you could so then you may have more abstract problems. As the weather, temperature, cloud cover and humidity changes, the signal propagates differnently and you will need to rotate your antennae from time to time. I have a straight shot from Alameda to Sutro but I have to rotate my 4228 about 30 degrees different between winter and summer due to weather issues. Chris the Antennae doctor has a great disscussion about this issue in the archives of the yahoo group HDTV-in-sfbay.
Other things that may need to be looked into are height of your antennae, the wiring to your STB (new RG-6 without any splitters can make a world of difference on a borderline signal) and experiemnting with a preamp like the 7777 which has a switchable FM filter.
Without a rotor, you are not going to be able to always stay "on target" for best signal. You may alslo be able to get some of the monterey stations.
The CC&R rules likely predate the changes to California state law allowing renters and owners to install roof dishes and antennae . No HOA is allowed to prevent you from installing any more. There is a great discussion by a lawyer about this on the yahoo group, including a form letter to use to "inform" your HOA you are going to exercise your legal rights and put up an antennae. Several renters and home owners have gone to court on this and have all won.
This is a partial post from June in anwswer to a guy from Almaden:
It quotes the national rule, not Ca state law.
The FCC ruling also allows you to put up an antenna as long as it's
mounted on an area of exclusive use or ownership. If your HOA pays for
all roof maintenance, you are likely not going to be able to mount it up
Seems to cover you even if you lease or rent, as long as the mount area is not a common area to your neighbors. Also no size restriction for a digital OTA antennae is defined so you can mount a 4228 if you want, but if you dont want to thumb your nose at them, maybe try the square shooter.
