San Francisco’s iconic Sutro Tower installed a Dielectric DCR-S Series FM radio antenna on its 977-foot-high steel structure, the antenna manufacturer announced.
With close to 300 current antennas, Sutro Tower is used by the San Francisco market’s top broadcasters—including 12 TV stations, four FM stations and 35 wireless radio communication users—to distribute their signals across the hilly, nine-county Bay Area region. First responders, government agencies, and transportation companies are also among the tower’s wireless radio users.
“We chose the Dielectric DCR-S FM antenna because of its broadband capabilities and excellent axial ratio characteristics,” said Sutro Tower COO Eric Dausman. “Because of our central location, the DCR-S antenna’s broadband and multi-channel capabilities, covering 88 to 98 MHz, enables us to multiplex signals and maximize our tower’s capacity.”
A consortium of four broadcasters has owned Sutro Tower since it was built in 1973. “Since Sutro Tower is surrounded by private homes, the structural integrity of our tower, and the mechanical design and construction of the equipment it supports, are extremely important to public safety,” Dausman said. “The tower, antenna and auxiliary systems need to be of high structural quality. The Dielectric antenna designs meet the consortium’s structural and electrical requirements, including robust products, with a decades-long lifecycle,” according to Dausman.
