The North American broadcast television frequencies are on designated television channels numbered 2 through 69, approximately between 54 and 806 MHz. Traditionally, the frequencies are divided into two sections, the very high frequency (VHF) band and the ultra high frequency (UHF) band. The VHF band is further subdivided into two more sections, VHF-Lo (band I) and VHF-Hi (band III). In between lie allocations for other services including the FM broadcast band (band II), bands used for land mobile radio, radio remote control, civil service agencies, amateur radio, and aircraft navigation aids and voice communication (airband).

Famous quotes containing the words north american, north, american, broadcast and/or television:
“We might hypothetically possess ourselves of every technological resource on the North American continent, but as long as our language is inadequate, our vision remains formless, our thinking and feeling are still running in the old cycles, our process may be “revolutionary” but not transformative.”
—Adrienne Rich (b. 1929)
“The North is full of tangled things and texts and aching eyes
And dead is all the innocence of anger and surprise,
And Christian killeth Christian in a narrow dusty room,
And Christian dreadeth Christ that hath a newer face of doom,
And Christian hateth Mary that God kissed in Galilee,”
—Gilbert Keith Chesterton (1874–1936)
“I make this direct statement to the American people that there is far less chance of the United States getting into war, if we do all we can now to support the nations defending themselves against attack by the Axis than if we acquiesce in their defeat, submit tamely to an Axis victory, and wait our turn to be the object of attack in another war later on.”
—Franklin D. Roosevelt (1882–1945)
“Radio news is bearable. This is due to the fact that while the news is being broadcast the disc jockey is not allowed to talk.”
—Fran Lebowitz (b. 1951)
“The television screen, so unlike the movie screen, sharply reduced human beings, revealed them as small, trivial, flat, in two banal dimensions, drained of color. Wasn’t there something reassuring about it!—that human beings were in fact merely images of a kind registered in one another’s eyes and brains, phenomena composed of microscopic flickering dots like atoms. They were atoms—nothing more. A quick switch of the dial and they disappeared and who could lament the loss?”
—Joyce Carol Oates (b. 1938)
