The height of WNGH-TV's transmitter gives it one of GPB's largest coverage areas. It penetrates for some distance into the area of Chattanooga, Tennessee; Chatsworth and Dalton are part of the Chattanooga media market. It provides at least secondary coverage as far north as Athens, Tennessee, and as far south as metro Atlanta's north-northwestern suburbs, many of which can no longer receive GPB's flagship station, WGTV (channel 8). Two translator stations help bring the signal to the mountainous parts of the service area. Some network program duplication occurs with WTCI-TV (channel 45), the main PBS station for the Chattanooga area.
