Although the station mainly serves the Kansas City area, it is officially assigned by Nielsen to the St. Joseph Designated Market Area (DMA) due to its city of license residing in the St. Joseph market. The station has been available on cable television providers in both the St. Joseph and Kansas City markets since its sign-on, although Charter Spectrum (in the immediate Kansas City area), Comcast Xfinity, Consolidated Communications, AT&T U-verse and Google Fiber do not carry KTAJ but do carry TBN's national feed.
