S27T Single Band Digital Repeater

Product Feature:


* High-quality aluminum alloy shell, good heating dissipation.
* Alarm LED indication.
* AGC function special for electric fans.
* Manual gain attenuation, with 1dB step to attenuate the gain among 1-30dB range.
* ALC could limit the output power to ensure stable coverage.
* Support 3 sub-bands and each bandwidth is with maximum 24MHz.

The repeater has Digital IF SAW filter technology. Support 3 sub-bands and each bandwidth is with maximum 24MHz.
It can be controlled and monitored, via RS232 connecting PC for local control, via GSM modem connecting PC for remote control, set the frequency and ATT of UL or DL, check the output power of UL or DL, and check the temperature alarm and ALC alarm via the OMT.
