Product Description
Apply to UHF interphone communication system or TETRA digital trunking communication system signal coverage extension.

Product Feature
1.One Donor Unit can link 4 Remote Units at most

2.Adopting Wavelength Division Multiplexing technology to realize long distance transmission via a fiber

3.Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink

4.Details repeater parameters and status monitor, such as RSSI, temperature, output power level, gain, ATT, return loss, VSWR etc.

5.Configure RS-232 ports to links to laptop for local test

6. Monitor the Remote Unit via Donor Unit.

7.Can choose SMS, GPRS or TCP/IP for remote monitoring.

Application / Models
Apply to UHF interphone communication system or TETRA digital trunking communication system signal coverage extension.
