BT 20 Dual[ENG]

The BT20 DUAL, both versions, is a professional dual band 2G-4G repeater for mobile telephone applications with high gain 60-65dB, automatic level control (ALC) and interference alarm.

It operates on two bands at the same time: 2G 900MHz and 4G 2100MHz (band 1) wide band for voice and data traffic both low speed GPRS-EDGE and high speed LTE data.
Typical capacity up to 20-30 simultaneous communications from outside building where signal is well operative to inside where poor or absent.

Very reliable and efficient, able to cover up to 1.500 square meters on the standard version; with kit splitter option and adequate project can be reached 2.000-3.000 square meters of indoor coverage.

Available more versions:

• The STANDARD (BT20 DUAL/STD) version uses an external panel antenna with high gain (14dBi) that must be directed to provider cell, to prefer where external signal is low.

• The OM (BT20 DUAL/OM) or multidirection version includes omnidirectional 360° antenna with limited gain (6dBi) but it is more practical to be used, usable only with good signal level on outside.

• If it is required multiproviders application with external signal very limited, or the application requires more indoor antennas, it is available external collinear antenna COL2 (2 panels) or COL4 (4 panels) with high gain and extension band.

Upgrade facility to 3-bands, 4-bands or 5-bands system by combined dualband base cards BCDS/BT20 LTE/BT14 (see pages 16-17).

Applications: shops, restaurants, offices, factories, houses, tunnels, underground car parks, etc.
