KGW (NBC) · Channel 8

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 1,000 kW effective radiated power, KGW runs more power than 79% of full-power TV stations nationwide (median: 273 kW).

Its antenna sits 539 m above the average surrounding terrain, higher than 78% of full-power stations. Taller antennas see farther: this one's radio horizon is roughly 67 miles, beyond which the signal fades quickly.

We estimate a fair-or-better signal out to about 78 miles with an outdoor antenna. That area includes 155 cities and towns in our guide with about 2,720,000 residents, as far as Corvallis, OR (71 miles).

KGW shares its transmitter site with KPXG-TV (ION), KGWZ-LD, KOPB-TV, KPXG-LD (ION), KORS-CD and KOXI-CD and 8 more. One antenna aimed at this site picks up all of them.

The nearest other NBC station in our data is KNDO in Yakima, WA, 128 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.
