WCSH (NBC) · Channel 6

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

Its antenna sits 588 m above the average surrounding terrain, higher than 85% of full-power stations. Taller antennas see farther: this one's radio horizon is roughly 70 miles, beyond which the signal fades quickly.

We estimate a fair-or-better signal out to about 81 miles with an outdoor antenna. That area includes 310 cities and towns in our guide with about 1,830,000 residents, as far as Merrimack, NH (79 miles).

The nearest other NBC station in our data is WBTS-CD in Nashua, NH, 110 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.
