無線電範圍擴展器，SR-328是一種多功能，更便宜的設備，可連接任何手持或移動無線電。
通過我們的組裝，新一代幹線板等設備，內部結構設計更精細，外觀更具吸引力。除了可以提供跟隨接收器發射器的基本中繼器功能外，還具有簡單連接，為您提供更理想的雙向無線通話區域，使您在更大的工作區域內保持關係。
這是一個無線電雙工中繼控制器。它是一種易於操作且經濟高效且高度靈活的平台，用於設置具有移動無線電和手持無線電的雙向頻帶雙工中繼器。
SR-328有2個音頻端口輸入和輸出，用於連接移動和手持無線電。提供密碼保護的DTMF遠程控制功能。用戶可以通過DTMF遠程控制轉發器的ON或OFF，LED顯示2無線電狀態，內置電池。

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.
