Radio
Band II ranges from 87.5 to 108.0 MHz, and it is primarily used worldwide for broadcasting service (FM sound broadcasting). It typically uses a dipole aerial, horizontally and vertically polarized, so it is both bidirectional, and omnidirectional on the horizontal plane.
Usage in Russia and in other former members of OIRT
In the former Soviet Union and other countries-members of OIRT, frequencies from 76 MHz to 100 MHz were designated for broadcast television usage. Considering 8 MHz channel bandwidth used by the Russian analog television system (System D), the following television channels had been defined:
Broadcast television channels 1 and 2 are assigned to VHF I band, channels 6 to 12 are assigned to VHF III band.
Starting from the early 1990-ies, frequencies previously allotted to television channels 4 and 5 have been re-allocated for FM radio, thereby harmonizing it with the Western allocation for FM radio service.
