Engineers at Sutro Tower in San Francisco will be doing their annual maintenance work 9am-4pm Mon 8/20 through Fri 8/24. All stations transmitting from Sutro Tower will be dropping to half-power each day, and perhaps moving from main antennas at the top of the tower to auxiliary antennas at the “waist” (middle) of the tower during daylight hours. Stations will move back to the top of the tower and full power at the end of each day’s work.
This work will not affect most Over The Air viewers. However, some folks at the outer reaches of the various TV signals may lose daytime TV, and will need to do a re-scan each evening after 4pm to restore their TV channels.
