Tri band repeater is to support any three mobile band existing in the world to help end users to improve mobile signals for much better phone call quality and smoother data transmission. It is designed to support coverage area max can up to 2000 square meters with proper engineering. 


1. With unique appearance design, have good cooling function

2. With LCD display , we can know the unit gain and output power clearly

3. With DL signal LED display, help to install the outdoor antenna at the best state;

4.With AGC and ALC, make repeater work stable .

5.PCB with isolation function ,make UL and DL signal not influence each other,

6.Low intermodulation, high Gain ,stable Output power


The consumer repeater is an ideal solution for providing a cost effective improvement in cellular in-building coverage of a home, office, restaurant or building, in the quickest time possible.
