For the purposes of its FCC correspondence, WKOI's official 'studio' facility is located at Scripps Center in downtown Cincinnati (along with many other Ion stations).
Until June 7, 2018,[4][5] WKOI-TV's transmitter was located on SR 73 in Milford Township, Butler County, Ohio, near Collinsville, approximately halfway between Richmond and Cincinnati.
It thus served as the TBN station for Northern Kentucky, East Central Indiana and a large swath of southwestern Ohio (Greater Cincinnati and the Miami Valley).
[7] WKOI-TV (along with all other TBN-owned full-power stations) shut down its analog signal, over UHF channel 43, on April 16, 2009.
The station's signal was multiplexed, carrying TBN on 43.1, The Church Channel on 43.2, JCTV on 43.3, Enlace on 43.4 and Smile of a Child on 43.5.
