The AM station's transmitter site is south of Zuehl, Texas, off Stolte Road. 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.
