WGBI-LP is a low-power television station licensed to Farmington, Maine. It is currently an affiliate of the Retro Television Network. The station broadcasts on UHF channel 21.


The station first signed on in June 1995 as W21BI, an owned-and-operated satellite repeater of the Trinity Broadcasting Network. Global Broadcast Network purchased the station in 2006, and changed the call letters to the current WGBI-LP. Upon flash-cutting to digital broadcasting on November 6, 2010, WGBI affiliated with RTV.

Prior to its current use, the call letters WGBI were used on radio and television stations in Scranton, Pennsylvania from the 1920s until 2005.[1]
