Beginning in the 1990s, KSBI gradually signed on a network of translator stations throughout the state. Eventually, because of this wide relay network, channel 52 claimed to have the largest broadcast coverage area of any commercial television station in Oklahoma; at its peak, its signal was relayed over fourteen translators serving areas within the Oklahoma City market and in markets adjacent to it such as Tulsa, Elk City, Ponca City and Ardmore. It also gained cable (and eventually, satellite) coverage in the Tulsa, Wichita, Amarillo, Lawton–Wichita Falls and Ada–Sherman markets. In August 1999, the station upgraded its transmitter from an effective radiated power of 1,355 kW to a total power of three million watts, after installing a new transmitter antenna atop the broadcast tower on 122nd Street and Kelley Avenue in northeast Oklahoma City.
