Repeater work:     
      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.
 


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  .)

Have  a 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 !
