KMSB-TV (Tucson, AZ)

KMSB, virtual channel 11 (UHF digital channel 25), is a Fox-affiliated television station licensed to Tucson, Arizona, United States. Owned by Tegna Inc., the station is operated by Gray Television (owner of CBS affiliate KOLD-TV, channel 13) through a shared services agreement (SSA); Gray also operates MyNetworkTV affiliate KTTU (channel 18) through a separate SSA with Tucker Broadcasting (with advertising sales handled by Tegna). The three stations share studios on North Business Park Drive on the northwest side of Tucson (near the Casas Adobes neighborhood). KMSB's transmitter is located atop Mount Bigelow; as a result of the transmitter's location, residents in the northern part of Tucson, Oro Valley and Marana cannot receive adequate reception of the station.
