BT-20D-COL2 GSM Repeater GSM900+3G, 2 directional antennas

The BT-20DUAL is used to extend the range of 900MHz and 3G/UMTS mobile phone networks in buildings. It can be used anywhere where the reception of mobile phone signals is blocked due to the construction of the building, but is available outside the building. The repeater is designed to work on two bands simultaneously, it supports the 900MHz GSM (2G) band as well as the 3G/UMTS band (2100MHz). With this the BT-20DUAL is perfect for coverage where voice (GSM) and data connections (GPRS, EDGE, HSPA, HSPA+) are required.

•  The standard model BT-20DUAL is equipped with an outdoor high gain directional antenna. This is receommended for normal distances to the base station.

• The model BT-20DUAL-OM has an outdoor omnidirectional antenna and is suitable when you have a) a good signal outdoors, and b) you need to contact different providers in different directions.

• The model BT-20DUAL-COL2 uses two directional outdoor antennas, which are combined to one cable with a splitter. Both antennas can point in one direction to achieve a higher gain, or point in different directions to contact different providers which are spatially distributed, or contact different networks (GSM, UMTS) of the same provider who uses multiple locations.

• The model BT-20DUAL-COL4 uses four directional outdoor antennas, which are combined to one cable with a splitter. The antennas can point in one direction to achieve a higher gain, or point in different directions to contact different providers which are spatially distributed, or contact different networks (GSM, UMTS) of the same provider who uses multiple locations.
