NO problem with looking at my antenna. When you do, you can disregard the horizontal Yagi antenna. That's just there to see if I can get the KNTV VHF signal from Mt. San Bruno whenever they get it up and running. I'm not counting on it, but since I had already purchased that Ch. 11 tuned antenna in a failed attempt to reach Loma Prieta, I doesn't cost anything to leave it there and try it later. You may notice that I'm higher than the valley floor of WC, which makes getting something from Sutro tower more likely.
If you want to know how it's mounted, I have the bottom of the mast clamped to a vent pipe, two of the three guy wires also attached to two other vent pipes, and the third guywire attached to a brace I mounted under the eave end next to the big redwood tree. With the CM4228 UHF antenna, it has a good sized "sail" to it, even if it is a screen. I would have had it come down in some recent storms, but that's because the wind can really whip around from the high ridge that's just behind my house. The way I attached it to the roof means I have nothing mounted on the roof surface itself. That keeps the roof intact. City building inspectors tell me there in not a problem attaching anything to a vent pipe like that, since it does not interfere with the venting. I drilled a small 3/16 "hole in the metal of the copper pipes and attached a small eye bolt for the guywires.
You might want to consider contacting an antenna installer who could test to see if you can get digital reception where you live, and if not, not charge you too much just for the testing. (assuming you can find one who will do it that way) I suspect getting the Sacramento stations on the Walnut Grove tower could also be a possiblilty for you, living out in the east valley of WC. You could take a look at the azimuth to those channels on the map available at antennaweb.org from your address, and see what kind of line of sight might exist, if you can get up to or close to roof level. You don't necessarily need line of sight, but more probably a good reflection from something someplace in between. If you can't get up high enough, that is at antenna height, look at your azimuth going the other way, and see if there is a hill behind you that you could look from over that along that same azimuth. A simple compass could really help that, since you can then duplicate that angle from anywhere nearby. I think the hills over near the small golf course on the west side of Heather farm might work, or even on the west side of the park near Marchbanks could do the same. Ideally you want to be where you can see what might be in the way toward Walnut Grove. Sometimes people can get a reflection from something that comes from a direction that can surprise you.
I had an installer give me a price for mounting an indentical antenna to mine on my chimney, with a two priced arrangement: works/doesn't work. It got mixed results, so I took his "not good (enough) reception" price, and thanked him for his efforts. (He's no longer in the business.) I then later purchased the same antenna myself, along with a CM7777 VHF/UHF premap (you may be able to see the first part of it mounted just below the top "screen reflector" antenna.) That boosts the signal strength right at that point, so a strong signal can get down my RG-6 lead-in coaxial cabling.
The power source for the preamp plugs into 110 near your HDTV receiver, and the cable runs first to it and then to the receiver. I tried mounting the antenna myself on the other end of my house using the vent pipes for mounting and guy wiring, and with a little tinkering around, wound up with some great reception off of Sutro.
Probably more than you wanted to know, but what the heck...
Being on the board of an HOA where I have a condo for my mom elswhere in WC, I know that HOA's need to allow for reasonable accommodation to allow for antennas or satellite dishes. The board reviews proposed installations, because not one set of rules can apply to each and every location, and allows the installations that minimize obtrusiveness while still being allowed for installation. Sometimes we suggest alternative locations for an antenna that minimizes its visibility, if that can be done without diminishing reception. HOAs should not let antenna installers mount antennas anywhere they want using whatever method, but they do have to allow for antennas where possible. I know about this because I wrote the rule for the HOA that covers those things, when the law changed that called for such accommodation.
BTW, the "drive-by" comment was "tongue-in-cheek". If you really want a closer look at it, try the doorbell and ask for me. I might be home.
If I'm not home, watch out for the rotweiler..............just kidding.

See, I really AM long-winded.
