KCBS-TV/FM Tower is a 296.4 meter high guyed radio/television tower on Mount Wilson above Los Angeles at 123 CBS Lane. The KCBS-TV/FM Tower was built in 1986. It was owned by CBS Corporation and used by KCBS-TV and KCBS-FM . When the DTV conversion was planned the CBS transmitters were installed in the Channel 9 building and combined onto one antenna. The guyed tower facility, the westernmost on Mount Wilson, was sold in November 2009 to Richland Towers whose headquarters is in Tampa, Florida.
