KRWB-TV (CW) · Channel 21

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, KRWB-TV runs more power than 79% of full-power TV stations nationwide (median: 273 kW).

Its antenna sits 128 m above the average surrounding terrain, higher than 3% of full-power stations. Taller antennas see farther: this one's radio horizon is roughly 37 miles, beyond which the signal fades quickly.

We estimate a fair-or-better signal out to about 51 miles with an outdoor antenna. That area includes 7 cities and towns in our guide with about 94,400 residents, as far as Carlsbad, NM (47 miles).

The nearest other CW station in our data is KOSA-TV in Odessa, TX, 130 miles away. Viewers between the two can sometimes receive both.

The CW is a commercial broadcast network carrying entertainment series and a growing slate of sports. In smaller markets it often runs as a subchannel of another station rather than its own transmitter.
