Greetwin Tri-Band High Gain Cellular Network Repeater 2g 3G 4G LTE Dcs B3 B7 B20 Signal Booster

A cellular network repeater (also known as an amplifier or booster) is an essential wireless system designed to enhance cellular reception. It consists of three primary elements: an exterior antenna, a signal amplifier, and an interior antenna.

This system works by capturing existing signals from the outside environment via the donor antenna, amplifying them through the signal booster, and then rebroadcasting the improved signal to indoor areas with weak or no reception. This process significantly reduces dropped calls and improves data speeds for workstations, offices, and homes.

Installation Steps:

1. Drill holes in the selected wall location and install expansion bolts.
2. Align the booster holes with the bolts and tighten nuts to fasten the support.
3. Connect the donor antenna cable to the BTS Port (Outdoor).
4. Connect the service antenna to the MS Port (Indoor).
5. Connect the DC power adapter and check operation status on the LED panel.
