WNAI-CD

WNAI-CD is the MyNetworkTV-affiliated station for the Fort Warren, FL television market. It operates an analog signal on channel 20 and a digital signal on physical channel 31, virtual channel 20 from a transmitter in Kernstown, leasing tower space with sister station WJSC. It's owned by Titan TV Broadcast Group, and operated by East Coast Broadcasting Company.

History
Construction and planning for channel 20 dates back to 1987 (same time as sister station WOKF-CD) but got more rushed with the announcement of UPN in 1993.

This rush in construction led to channel 20 signing on a little less than a year before UPN's launch. WNAI launched on March 3, 1994 (nearly 2 months after WOKF) as W20FF. Until UPN launched, W20FF acted as a translator for WOJH.

WNAI became the charter UPN affiliate for the Fort Warren market upon that network's launch in January 1995. A year later, it changed its call letters to WNAI-CA. It originally identified itself on air as "UPN 20," but it was later changed to "UPN Fort Warren." This was done because virtually all of its viewership was on cable, and the cable position was considerably lower than channel 20. This is not to mention that the WOJH simulcast Viewers were often confused about the "UPN 20" branding.

WNAI became a charter affiliate of MyNetworkTV when it launched in September 2006. It continued to run UPN programs on a secondary basis for about another week.

Digital Television
WNAI-CD1 broadcasts in 1080i rather than MyNetworkTV's native 720p format. WNAI-CD2 is simulcast on the main channel (in both analog and digital) during overnights and periodically on weekends

WNAI has plans to shut down its analog signal and convert to all-digital. It's unknown when these plans will be carried out.

Newscasts
WNAI will carry preempted newscasts on WJSC in the event that a network event spills over into that timeslot. Otherwise, it doesn't carry any special newscasts exclusive to the station.
