I have 21 year old 8 foot VHF/UHF antenna on my roof. It's about 55 feet high. While I have a rotor it's not necessary for Sacramento only stations. My quest is to reliably pick up the SF stations. So far I tried the monster Radio Shack VU-210 which while stronger was not strong enough. In mid-Stockton so I'm about 27 aerial miles from Sacramento's Walnut Grove towers but it's 65 miles to the Sutro towers in SF. My quest is on hold for the moment.
