Sutro Tower is the Bay Area’s most visible icon. Antennas on the 977-foot-high steel tower safely deliver clear signals throughout the San Francisco Bay Area for television and radio stations; essential communication services for public safety, transportation and other agencies or private providers; and unique, non-stop transmission opportunities for emerging technologies.

Sutro Tower is used by 10 television stations, 3 FM radio stations, satellite and cable providers, and nearly two dozen public and commercial wireless communication services.

Signals originate from each TV station’s studio, are delivered to the Sutro Tower transmission building by microwave or fiber optic cable, amplified in its transmitter equipment and sent up the tower to the antenna, which transmits the signal throughout the region.

Sutro Tower is owned by Sutro Tower Inc., which manages the structure and the leasing and use of its spaces.
