Ten television stations, three FM radio stations, and 20 wireless and mobile communications users (i.e. law enforcement agencies, taxi cabs, school buses, wireless internet, etc.) rely on Sutro Tower antennas to transmit signals over the air to the entire Bay Area.
For some reason it never occurred to me that Sutro was still a live radio tower - it’s such an SF landmark that I think I just assumed it was decommissioned or something.
