KMYU, virtual channel 12 ( VHF digital channel 9), is a primary MyNetworkTV- affiliated television station located in St. George, Utah, United States. The station is owned by Sinclair Broadcast Group, as part of a triopoly with Salt Lake City-based CBS affiliate KUTV (channel 2) and independent station KJZZ-TV (channel 14). KMYU and KUTV share studio facilities located on South Main Street in downtown Salt Lake City, and KMYU's transmitter is located atop Webb Hill south of downtown St. George. For official FCC purposes regarding a studio location in its city of license, KMYU has their studios in the J.C. Snow Building on East St. George Boulevard in downtown St. George, which also serves as KUTV's southern Utah news bureau.
As the broadcasting radius of KMYU's signal from St. George does not reach Salt Lake City due to its transmitter being located in the southern portion of the state, the station is simulcast over KUTV's second digital subchannel in order to reach that portion of the market, airing on virtual channel 2.2 from KUTV's transmitter located at Farnsworth Peak in the Oquirrh Mountains, southwest of Salt Lake City; similarly, because of the location of KUTV's transmitter, KMYU relays that station's signal on its second digital subchannel to provide over-the-air service of KUTV's CBS service to St. George. Many of KUTV's statewide digital translator stations also distribute both KUTV and the KMYU 2.2 simulcast to the northern and eastern portions of the state.
