The J.C. Phelan Company has been working on communication towers for
more than 50 years. We installed antennas and feed lines on San Francisco's
landmark Sutro Tower. The tower is 980 feet tall and is located on
Mount Sutro, which rises 920 feet above San Francisco.
In recent years, we have been contracted by several national wireless
carriers to work on towers throughout California. We have worked on
waveguides and other equipment mounted on towers.
