KFPX-TV (ION) · Channel 39

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 270 kW effective radiated power, KFPX-TV runs more power than 50% of full-power TV stations nationwide (median: 273 kW).

Its antenna sits 564 m above the average surrounding terrain, higher than 81% 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 76 miles with an outdoor antenna. That area includes 100 cities and towns in our guide with about 889,000 residents, as far as Fort Dodge, IA (55 miles).

KFPX-TV shares its transmitter site with KCCI (CBS), WOI-DT (ABC), KDIN-TV and WHO-DT (NBC). One antenna aimed at this site picks up all of them.

The nearest other ION station in our data is KPXR-TV in Cedar Rapids, IA, 95 miles away. Viewers between the two can sometimes receive both.

ION Television is a commercial network built around crime and procedural drama series, with some live sports. It is carried free over the air in most large markets.
