I reside on the east side of Sacramento County and will be installing a new UHF antenna on top of my 2-story home for my OTA Digital/HDTV stations on Thursday. The Walnut Grove transmitters are @35 miles from my home. I currently have a Radio Shack UHF Yagi antenna mounted in my garage that performs well for most channels but when I want to watch NBC it is not very stable. At first I was considering a Channel Master 4-Bay model, but then I began thinking about an 8-Bay model if it would help me pull in KTVU's digital signal (channel 56) out of San Francisco. I am a huge SF Giants fan and most, if not all of their games are broadcast on this channel. The paperwork on this antenna says it is good for only 60 miles but I believe the tower for SF broadcasts is closer to 100 miles away. Is there anyone out there living in my vicinity that can shed some first hand knowledge on this thought? Can I get SF from Sacramento? If so, do I need a rotor or will I be close enough to the line of site of both sets of transmitters?
