WTPC-TV (Trinity) · Channel 21

Full-power stations are the main licensed broadcasters in a market. They may run the highest power from the tallest towers and are protected from interference, so they set the core of what you can receive.

At 85 kW effective radiated power, WTPC-TV runs more power than 36% of full-power TV stations nationwide (median: 273 kW). Stations on VHF channels are licensed at much lower power than UHF stations to cover the same area, so a low figure does not always mean a weak signal.

Its antenna sits 310 m above the average surrounding terrain, higher than 33% of full-power stations. Taller antennas see farther: this one's radio horizon is roughly 53 miles, beyond which the signal fades quickly.

We estimate a fair-or-better signal out to about 58 miles with an outdoor antenna. That area includes 47 cities and towns in our guide with about 1,940,000 residents, as far as Petersburg, VA (57 miles).

WTPC-TV shares its transmitter site with WGNT, WHRO-TV, WTVZ-TV and WTKR (CBS). One antenna aimed at this site picks up all of them.

The nearest other Trinity station in our data is WHSG-TV in Monroe, GA, 491 miles away. Viewers between the two can sometimes receive both.

Trinity Broadcasting Network (TBN) is a Christian religious broadcaster with a large network of owned stations and translators.
