KFNB (Fox) · Channel 20

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 52.4 kW effective radiated power, KFNB runs more power than 30% 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 560 m above the average surrounding terrain, higher than 80% of full-power stations. Taller antennas see farther: this one's radio horizon is roughly 68 miles, beyond which the signal fades quickly.

We estimate a fair-or-better signal out to about 70 miles with an outdoor antenna. That area includes 6 cities and towns in our guide with about 79,000 residents, as far as Casper, WY (9.0 miles).

KFNB shares its transmitter site with KTWO-TV (ABC), KGWC-TV (CBS), KCBZ-LD, KWYF-LD and KPTW. One antenna aimed at this site picks up all of them.

The nearest other Fox station in our data is KFNR in Rawlins, WY, 81 miles away. Viewers between the two can sometimes receive both.

Fox is one of the four big commercial broadcast networks, known for its sports lineup including NFL, MLB and college football. Many Fox affiliates also produce local news.
