What is Included?
[1] 900+1800+2100 mhz Tri Band Repeater Base Unit
[2] AC Power Cord
[3] Outdoor Log-periodic Antenna
[4] Indoor Celling Antenna
[5] 20 +5 Meters White Coax. Cable
The repeater makes the signal stronger in places with poor signal coverage such as:
1) Underground areas: basements, parking lots, tunnels;
2) Other places where cellular signal is shielded by metal or concrete walls: offices, supermarkets, cinemas, hotels;
3) Places distant from the BTS like private houses.
How it works?
1. Received a good outdoor signal from signal tower.
2. Cable transmits good signal to repeater.
3. Signal Booster enhance the received signal.
4. Improve indoor's cellphone signal.
