About WDSI-TV
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 120 kW effective radiated power, WDSI-TV runs more power than 40% of full-power TV stations nationwide (median: 273 kW).
Its antenna sits 306 m above the average surrounding terrain, higher than 31% of full-power stations. Taller antennas see farther: this one's radio horizon is roughly 52 miles, beyond which the signal fades quickly.
We estimate a fair-or-better signal out to about 59 miles with an outdoor antenna. That area includes 84 cities and towns in our guide with about 810,000 residents, as far as Dalton, GA (33 miles).
WDSI-TV shares its transmitter site with WTVC (ABC), WFLI-TV (CW) and WRCB (NBC). One antenna aimed at this site picks up all of them.
