KIRO-TV (CBS) · Channel 7

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 715 kW effective radiated power, KIRO-TV runs more power than 70% of full-power TV stations nationwide (median: 273 kW).

Its antenna sits 257 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 (54 miles).

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

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

CBS is one of the four big commercial broadcast networks. Local CBS affiliates carry the network's news, daytime and primetime schedule plus local news, and CBS is the over-the-air home of many NFL Sunday afternoon games.
