KTKB-LD, virtual and UHF digital channel 26, is a low-powered CW+-affiliated television station serving the U.S. territory of Guam that is licensed to Tamuning. Owned by Chicago-based KM Communications, the station is operated by Marianas Media under a local marketing agreement (LMA). It is carried island-wide on cable channel 4 on MCV Broadband and GTA's GUdTV system (hence the CW 4 Guam branding). Despite being a low-power television station, KTKB's signal covers all of Guam. It is also the territory's first fully digital commercial television station.
