WKBS-TV is a Christian television station serving the Allegheny area of Pennsylvania that is licensed to Altoona. It broadcasts a digital signal on UHF channel 46. Owned by Cornerstone Television, the station is effectively a satellite of Cornerstone's flagship station, WPCB-TV in Pittsburgh.
In 1983, Cornerstone Television was granted a construction permit for channel 47 in Altoona, Pennsylvania to serve the Johnstown/Altoona market. It bought the transmitter used by the original WKBS-TV (channel 48) in Philadelphia when that station went dark in 1983, and used this transmitter to put channel 47 on the air November 2, 1985, reusing the WKBS-TV callsign.

WKBS-TV shut down its analog signal, over UHF channel 47, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 46. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 47.
