WBNA (channel 21) is an independent television station in Louisville, Kentucky, United States, owned by local charismatic megachurch Evangel World Prayer Center.

As such, WBNA is the only full-power television station in the Louisville market whose transmitter facilities are not based at the Kentuckiana tower farm in Floyds Knobs, Indiana.

After seven years of construction and technical errors, WBNA finally signed on the air on April 2, 1986, as the second full-power independent station in the Louisville market.

Rodgers gave credit to Louisville engineer Clarance Henson for helping guide the church through the whole process of finally getting switched on.

[2][a] WBNA's sign-on marked the first signal on analog channel 21 in Louisville since the demise of WKLO-TV, which operated as a dual ABC/DuMont affiliate from October 1953 through April 1954.

[2]: 282  Broadcasting this programming format did not come without risks as Christian-oriented television became a depressed market due to recent scandals involving televangelists.

However, Evangel felt chagrin at The WB's decision to pick up several programs that it believed offended the sensibilities of channel 21's mostly fundamentalist and Pentecostal viewership, such as nighttime soap Savannah, supernatural dramas Charmed and Buffy the Vampire Slayer and sitcom Unhappily Ever After.

WBNA's lower power signal and shorter antenna tower in Bullitt County, Kentucky (shorter due to its relative position to the approaches to the two NNE-SSW runways at Louisville International Airport), delivers a much weaker city signal than the other full-power DTVs (and many low-power and Class A stations), which transmit from the 900-foot (274 m) bluffs of Floyds Knobs, Indiana.

As part of the SAFER Act,[11] WBNA kept its analog signal on the air until June 26 to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters.
