In North America, terrestrial television is
broadcast
on designated channels numbered 2 through 69. Except for a few instances, consumer televisions and recorders come with these frequencies pre-programmed in, as opposed to what sometimes occurs in other places around the world. Traditionally, the frequencies are divided into two sections, the very high
frequency
(VHF) band and the ultra high
frequency
(UHF) band, but in reality, the VHF band is further subdivided into two more sections, VHF-Lo (band I) and VHF-Hi (band III). In between lies the FM band (band II) used for
frequency
-modulated radio transmissions and a VHF radio band typically used by civil service agencies, amateur radio and aircraft (often called the airband).
