KSAH (720 kHz) is a commercial AM radio station, licensed to Universal City, Texas, and serving the San Antonio metropolitan area. KSAH and sister station 104.1 KSAH-FM simulcast a classic regional Mexican radio format, specializing in norteño music. The two stations are owned by Alpha Media with the licenses held by Alpha Media Licensee, LLC. The studios and offices are located on Eisenhauer Road in Northeast San Antonio.

The AM station's transmitter site is south of Zuehl, Texas, off Stolte Road.^[2] By day, KSAH is powered at 10,000 watts. But because AM 720 is a clear channel frequency reserved for Class A WGN Chicago, KSAH must reduce power at night to 890 watts to avoid interference. The station uses a directional antenna around the clock.
