4. Indoor Omni antenna
5. Indoor Ceiling antenna
5. 5 meters cable
6. 20 meters 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.
