When used with one of our DHF compatable master clocks, the DHF transmitter is used to transmit wireless DHF a time code via a radio transmitter. The DHF clocks, melodies and wireless relays automatically synchronise when receiving the transmitted time signal. The DHF signal of 869 MHz (high frequency) can be received through building walls and broadacsts can be covered over an area: 100 to 200 metres depending on number, structure and thickness of the walls.
It can also travel up to 1km in open space. If there is an area, or part of a building where the signal cannot reach, this can be overcome by the use of our DHF Repeaters (signal boosters).
