KSTU (Fox) · 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 350 kW effective radiated power, KSTU runs more power than 54% of full-power TV stations nationwide (median: 273 kW).

Its antenna sits 1,210 m above the average surrounding terrain, higher than 99% of full-power stations. Taller antennas see farther: this one's radio horizon is roughly 97 miles, beyond which the signal fades quickly.

We estimate a fair-or-better signal out to about 103 miles with an outdoor antenna. That area includes 142 cities and towns in our guide with about 2,730,000 residents, as far as Logan, UT (77 miles).

KSTU shares its transmitter site with KUCW (CW), KSL-TV (NBC), KBYU-TV, KUTV (CBS), KJZZ-TV and KTVX (ABC) and 8 more. One antenna aimed at this site picks up all of them.

The nearest other Fox station in our data is KSVT-CD in Twin Falls, ID, 183 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.
