WSAW-TV is the CBS- affiliated television station for North-Central Wisconsin's Northern Highland. Licensed to Wausau, it broadcasts a high definition digital signal on VHF channel 7 from a transmitter on Rib Mountain. Owned by Gray Television, the station is sister to low-powered Fox affiliate WZAW-LD and the two outlets share studios on Grand Avenue/ U.S. 51 in Wausau.
To serve the Northwoods area of Northern Wisconsin, it operates a digital fill-in translator in Sayner (W42DH-D) that also covers Eagle River. This also airs a high definition signal but is seen on UHF channel 42 (or virtual channel 7.1 via PSIP) from a transmitter, on Razorback Road, in unincorporated Vilas County (north of Sayner). The low-powered repeater also serves the western portion of Michigan's Upper Peninsula although the broadcasting radius is limited to Marenisco and Watersmeet.
