The Motorola SLR 8000 Repeater


Two Way Radio Base Stations and Repeaters

A radio repeater is a combination of a radio receiver and a radio transmitter that receives a weak or low-level signal and retransmits it at a higher level or higher power. The result: two-way radio signals can cover longer distances without degradation. Repeaters are usually located on a mountain top, tall building, or radio tower. This allows communication between two or more bases, mobile or portable stations that are unable to communicate directly with each other due to distance or obstructions between them.

The repeater is synonymous with the base station, which performs both functions in most emergency dispatching systems.

The repeater receives on one radio frequency (the “input” frequency), demodulates the signal, and simultaneously re-transmits the information on its “output” frequency. All stations using the repeater transmit on the repeater’s input frequency and receive on its output frequency.

Because the transmitter and receiver are on at the same time, isolation must exist to keep the repeater’s own transmitter from degrading the repeater receiver. If the repeater transmitter and receiver are not isolated well, the repeater’s own transmitter desensitizes the repeater receiver. This is like not being able to hear a friend at lunch because someone just turned up the volume on the kitchen radio.
