KNWA-TV (NBC) · Channel 51

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 820 kW effective radiated power, KNWA-TV runs more power than 74% of full-power TV stations nationwide (median: 273 kW).

Its antenna sits 260 m above the average surrounding terrain, higher than 19% of full-power stations. Taller antennas see farther: this one's radio horizon is roughly 49 miles, beyond which the signal fades quickly.

We estimate a fair-or-better signal out to about 61 miles with an outdoor antenna. That area includes 82 cities and towns in our guide with about 688,000 residents, as far as Nixa, MO (57 miles).

KNWA-TV shares its transmitter site with KXNW. One antenna aimed at this site picks up all of them.

The nearest other NBC station in our data is KSNF in Joplin, MO, 57 miles away. Viewers between the two can sometimes receive both.

NBC is one of the four big commercial broadcast networks. Local NBC affiliates carry the national morning show, evening news and primetime lineup, plus Sunday Night Football and, in Olympic years, the Games.
