In repeater systems, +5 MHz offset (split) is used, repeater output frequency on the lower frequency. The 5 MHz offset is standard for 450-470 MHz. Many business users operate simplex on either frequency, this is legal if the license specifies mobile operation on the given frequency.

Radar-frequency bands according to IEEE standard [17] Band designation Frequency range Explanation of meaning of letters; HF: 0.003 to 0.03 GHz: High frequency [18] VHF: 0.03 to 0.3 GHz: Very high frequency [18] UHF: 0.3 to 1 GHz: Ultra-high frequency [18] L: 1 to 2 GHz: Long wave S: 2 to 4 GHz: Short wave C: 4 to 8 GHz: Compromise between S ...
Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. [1] Because radio propagation does not stop at national boundaries, governments have sought to harmonise the allocation ...
Sources differ on the exact frequency range of the band. For example, the Swiss Federal Office of Communications, [1] the Broadcast engineer's reference book [2] and Ericsson India Ltd [3] all define the range of Band IV from 470 to 582 MHz. An EICTA paper [4] defines the range as 474 to 602 MHz, whilst the BBC define the range as 470 to 614 ...
American radio amateurs may use a maximum of one watt of radiated RF power, on any ham frequency authorized for data emissions, to control RC models. [10] Canadian radio amateurs may use any amateur frequency above 30 MHz for the control of RC models. [11] Plus or minus 5 MHz is a common repeater frequency offset in the 70 cm band.
The 70-centimeter band (420-450 MHz) is the most commonly used ham band for ATV. Signals transmitted on this band usually propagate longer distances than on higher frequency bands, for a given transmitter power and antenna gain. The band falls between broadcast TV channels 13 and 14, which are 210–216 MHz and 470–476 MHz respectively ...
