Product Description

Radio Range Extender,The SR-328 is a multi-function and cheaper device that connects any handheld or mobile radio.
By equipment and so on our assemble the build, the new generation trunk-line board, the internal structure design are finer, the outward appearance is more attractive. Besides can provide a  the basic repeater function which has following the receiver transmitter, furthermore has the Simple connection, provides the more ideal 2-way radio conversation region for you, causes you maintains the relation in the bigger operating region.

This  is a radio duplex repeater controller. It is an easy of operation and  cost effective and highly flexible platform for setting up bi-direction  band duplex repeater with mobile radio and handheld radio.  .

The SR-328 has 2 audio ports input and out , they are used to connect with mobile and handheld radio. DTMF remote control function with password protection is available in the . User can control the repeater ON or OFF remotely by DTMF. Multi-LED display 2 of radio status , and  build-in battery Level.

How to connector Radio :

A Input  for Radio Received         

B Input  for Radio Transmit

1, The frequency difference between the upper and lower row forwards (and conventional repeater), A machine as a signal uplink receiver, B machine as a signal downlink transmitter. In order to achieve the purpose of the relay.

 

 

When the radio units are connected, the received signal on a radio unit will be real time transmit on the other radio unit.  ,

 

 

Example 1 . Without duplexer and filter
Not have a duplexer : two hand-held units connected to a relay station, such as unparalleled workers, two hand sets should be separately using two antennas! Two antennas should be perpendicular to erect! And try to pull the distance between the two! At least not less than 1-5 metre (suggest : the farther the better two distance are Two antenna  .)
 Radio relay stations in different frequency duplex mode, that is, after receiving the weak signal of a specific frequency emitted far, immediately after synchronization will amplify and transmit the signal power to use another frequency. Who had set up a relay station people are aware, if not diplexers, height and level with two receiving antennas erected distance does not separate, not meet the technical requirements, the relay station is either not working due to self-excited work, or is "call far." This is because the weak signal relay station forwards the signal power at the time, it would be forwarded "drown" the adjacent repeater receiver front-end is a strong signal "closed."

 

Example 2 . With duplexer
purchase the corresponding frequency / power duplexer using "the joint " of the two hand sets connected to the antenna output terminal of the duplexer transmitter and receiver, respectively, set the frequency corresponding to the handheld units (frequency should be consistent with the duplexer). Under diplexer case, the relay station as long as the need to connect an antenna! And no special attention when erecting antennas !
