UHF channel 45 began its operations on June 1, 2001, carrying 3ABN, the religious U.S.-based network of Seventh-day Adventist Church.
Initially aired as a blocktime program at select times, it later became available as a dedicated digital channel on terrestrial television in 2015.
From being a religious affiliate, Gateway leaned away from its privilege and converted into a basic blocktime broadcaster in mid-2017 by carrying Global News Network programs on its digital signal.
Later, Gateway quietly ended its direct ties with 3ABN; instead, the main/analog service carries a separate Hope Channel PH's programming as well as other archived Adventist content.
The analog service then limited programming at nighttime, although its signal remains active daily from morning to midnight.
