A repeater is an automatic radio-relay station, usually located on a mountain top, tall building, or radio tower. It 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.

2023年10月2日 · A radio repeater is an electronic device that combines a radio receiver and a radio transmitter to receive a signal and retransmit it over a greater distance, allowing two-way radio communications to go further.

What is a Repeater? A repeater is an automatically controlled transmitter and receiver that simply transmits what the receiver hears simultaneously. Imagine having a receiver on one frequency, and a high power transmitter on a second frequency with …

A repeater receives a signal on one frequency and simultaneously retransmits (repeats) it on another frequency. The frequency it receives on is called the input frequency, and the frequency it transmits on is called the output frequency. To use a repeater, you must have a transceiver that can transmit on the repeater's input frequency and

A radio repeater retransmits a radio signal. In telecommunications, a repeater is an electronic device that receives a signal and retransmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction.

A radio repeater is a receiver and a transmitter that receives a signal and retransmits it to cover longer distances. A repeater at a high elevation enables radios without line-of-sight to communicate.

What: It's a two-way radio system that receives on one frequency, then re-transmits what it receives on another frequency; at exactly the same time. It's nothing more than a "dumb electronic machine" with some smart people behind it.

A repeater is an extremely powerful radio. Portable radios work in five watts, mobile radios work in 25 watts or more, and repeaters are even more powerful radios in the 50 to 100 watt range. Repeaters are generally in fixed positions at particular geographical locations.

2019年12月8日 · Repeater type radio systems are a special kind of duplex radio system, where a repeater station listens on one frequency (the Input frequency) and simultaneously retransmits the signal it receives on another frequency (the Output frequency). All of the mobiles and base stations listen on the repeater output frequency and transmit on its input ...

A repeater enables two-way radios to achieve better coverage, better penetration, and longer range than is possible without a repeater. How does it work? A repeater receives the radio signal on one frequency and simultaneously transmits the same signal on another frequency.
