KOMO-TV (ABC) · Channel 4

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 915 kW effective radiated power, KOMO-TV runs more power than 77% of full-power TV stations nationwide (median: 273 kW).

Its antenna sits 259 m above the average surrounding terrain, higher than 18% 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 219 cities and towns in our guide with about 4,140,000 residents, as far as Mount Vernon, WA (55 miles).

KOMO-TV shares its transmitter site with KUNS-TV (CW), KING-TV (NBC), KONG, KRUM-LD, K20NF-D and KIRO-TV (CBS) and 2 more. One antenna aimed at this site picks up all of them.

The nearest other ABC station in our data is KATU in Portland, OR, 147 miles away. Viewers between the two can sometimes receive both.

ABC is one of the four big commercial broadcast networks. Local ABC affiliates carry the national morning, evening news and primetime schedule alongside their own local newscasts, and the network carries major sports such as NBA games.
