WGTU is an ABC-affiliated television station licensed to Traverse City, Michigan, United States, serving the northern Lower and eastern Upper peninsulas of Michigan. It broadcasts a high definition digital signal on virtual and UHF channel 29 from a transmitter east of Kalkaska. Owned by Cunningham Broadcasting, WGTU is operated through a local marketing agreement (LMA) by the Sinclair Broadcast Group, making it a sister station to Traverse City-licensed NBC affiliate WPBN-TV, channel 7 (and its Cheboygan-licensed full-time satellite WTOM-TV, channel 4). However, Sinclair effectively owns WGTU as the majority of Cunningham's stock is owned by the family of deceased group founder Julian Smith. The two stations share studios on M-72 just west of Traverse City.
Like other network affiliates in this vast and mainly rural area, it operates a full-time, full-power satellite, WGTQ. Licensed to Sault Ste. Marie, this station broadcasts a high definition digital signal on virtual and VHF channel 8 from a transmitter approximately 30 miles (48 km) south-southeast of Sault Ste. Marie near Goetzville in southeastern Chippewa County. Together, the two stations are known on-air as ABC 29&8 and serve the largest television market by land area east of the Mississippi River: 23 counties in the Northern Lower Peninsula, three counties in the Eastern Upper Peninsula, and portions of Northern Ontario including Sault Ste. Marie's Canadian sister city.
