FM broadcasting
VHF Radio waves do not travel far beyond the visual horizon, so reception distances for FM stations are usually limited to 30–40 miles (50–65 km) They can also be blocked by hills or buildings.
CIUT-FM
Today, CIUT broadcasts at 15 kilowatts from a transmitter on the top of First Canadian Place in Downtown Toronto. With greater signal power than generally found at other community radio stations, CIUT's broadcast reaches as far as Barrie to the north, Buffalo to the south, Kitchener to the west and Cobourg to the east.
