Product Description
CDMA 850 3G 2100mhz cell phone signal booster indoor high gain dual band repeater amplifier Product Description There are millions of very small areas (10~150 square meters) where people work or live in and suffer from very poor or no mobile signals. People are seeking a cheap and immediate solution that would allow them have clear phone calls or higher speed broad band. However most of the current repeater solutions usually have larger coverage size, which is cost effective.
ST-82A is specifically designed as a "CHEAP" solution to meet this request.
1. The consumer repeater is an ideal solution for providing a costeffective improvement in cellular in-building coverage of a home, office, restaurant or building, in the quickest time possible.
2. Manual gain control (MGC total 31dB range with all DIP switches for each link) available for both uplink and downlink to adjust the gain value for proper coverage during installation or maintenance.
3. To maintain safe and specific output signal levels and give alarms on self-oscillation, the repeater has built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.
4. Auto shut off function available for both uplink and downlink to avoid deep self-oscilation from jamming the towers, saving your trouble from operators.
5. It supports two systems of CDMA850 and PCS 1900mhz.
Application place Application places of signal boosters
1. For large buildings such as stores, offices, school, company headquarters, warehouse and so on
2. For small Houses that in remote place 3
3. For vehicle (Car, Truck, RV)
4. For public place, for example: Metro, Tunnel, Hotel, Pub, Supermarket, etc
5. Gas Station, Gas Filled Station, Oil Field, Oil Depot
Specification Advantages:
1. Smart Function, Intelligent mode setting smart function called which can be activated via the front panel. users can adjust gain and choose working band by LED panel, This smart function is easier than DIP Switch, can set up parameters,It is a simple, safe and effective way.
2. Auto Level Control The 30dB ALC is used to maintain steady output power even when the donor source signal fluctuates.

Installation
Installation Steps
1 Use of mobile phones at the top of building or around the building to check out the direction of the strongest signal location.
2 Select the appropriate location, and put the outdoor antenna fix to the wall or bracket.
3 Select the appropriate location of the indoor locations (this location could be best that close to power and a well-ventilated place, sun-proof, rain-proof) Install the Indoor Repeater, and fix on wall or bracket.
4 Put the outdoor antenna to the "OUT DOOR" connector and tightens it. Thus complete the outdoor antenna and Repeater's connection.
5 After setting the suitable location of the indoor antenna and the installation place, then fixing the antenna.
6 The indoor antenna and Repeater wiring, the indoor antenna connect one end of the interface and on the other end connect Repeater's "IN DOOR" port.
Installation sketch Adjusting illustration A Proper adjustment of the antenna's position so that the best communication quality and signal strength. B Indoor antenna installed location should stay away from one end of the outdoor antenna, so as not to interfere with each other. (The outdoor antenna away from the indoor antenna placed above a layer of floor is better) C Indoor antenna should be installed above the height of 2 m of the ceiling or the corner. D Using the waterproof tape to wrap where has connector, so as to avoid oxidation caused by moisture, resulting in reduced indoor signal coverage.
