1, Profile
ET-BSG20S-F model can support GSM Band selective system. The bandwidth can be customized in the frequency range.
2, Features
Elegant and Compact design
Built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.
31dB MGC(Manual gain control) 1dB one step available for both uplink and downlink to adjust the gain value for proper coverage during installation or maintenance.
Auto shut off function available for both uplink and downlink to avoid deep self-oscillations from jamming the towers, saving your trouble from operators.
