KTMF (ABC) · Channel 23

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 92.6 kW effective radiated power, KTMF runs more power than 37% 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 642 m above the average surrounding terrain, higher than 91% of full-power stations. Taller antennas see farther: this one's radio horizon is roughly 73 miles, beyond which the signal fades quickly.

We estimate a fair-or-better signal out to about 76 miles with an outdoor antenna. That area includes 22 cities and towns in our guide with about 120,000 residents, as far as Missoula, MT (10 miles).

KTMF shares its transmitter site with K08PR-D, KECI-TV (NBC) and KPAX-TV (CBS). One antenna aimed at this site picks up all of them.

The nearest other ABC station in our data is KWYB in Butte, MT, 102 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.
