WIRT-DT (ABC) · Channel 13

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 13 kW effective radiated power, WIRT-DT runs more power than 7% 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 204 m above the average surrounding terrain, higher than 10% of full-power stations. Taller antennas see farther: this one's radio horizon is roughly 44 miles, beyond which the signal fades quickly.

We estimate a fair-or-better signal out to about 45 miles with an outdoor antenna. That area includes 13 cities and towns in our guide with about 61,200 residents.

WIRT-DT shares its transmitter site with WRPT and K15GT-D. One antenna aimed at this site picks up all of them.

The nearest other ABC station in our data is WDIO-DT in Duluth, MN, 57 miles away. Viewers between the two can sometimes receive both.

ABC is one of the four big commercial broadcast networks. Local ABC affiliates carry the national morning, evening news and primetime schedule alongside their own local newscasts, and the network carries major sports such as NBA games.
