Overview:
SY -D**-** dual system signal repeater series are designed for private users or business places indoor coverage solution.
Such as the big house of end user, the bookstore, the restaurant, the coffee shop, the KTV, the bar, the parking pot, the super market, big office or Using a revolutionary, patent pending technology that protects the carrier network, the dual system repeater improves indoor cell phone signals by capturing and repeating the outside signals, bringing them into the building and enhancing them.
This is wide band consumer level repeater.  
Operation Frequency bands:
-
LTE800
- GSM900 & EGSM
- DCS1800 / LTE1800
- WCDMA2100 UMTS2100/ LTE2100
- LTE2600
- and so on
Any combinations of selected 2 bands are possible.
So on request are possible combinations : L8+G, L8+E, L8+D, L8+D, L8+W, L8+L26, G+D, G+W, G+L26, E+D, E+W, E+L26, D+W, D+L26, W+L26
Features:
1. Elegant and Compact design
2. Built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.
3. 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.
4. Auto shut off function available for both uplink and downlink to avoid deep self-oscillations from jamming the towers, saving your trouble from operators.
5. Low power consumption.
6. Coverage
SY-D15-** model has a 300 ~ 1200sq.m coverage.
SY-D20-** model has a 900 ~ 2000sq.m coverage.
SY-D23-** model has a 1200 ~ 2500sq.m coverage
Signal repeater can combine with trunk Amplifier to realise bigger area's coverage.
