Special Features:

Bi-directional variable gain dual band cell phone signal booster; frequency: uplink 824-849 mhz and 1850-1910 mhz, downlink 869-895 mhz and 1930-1990 mhz; model da4000 includes antenna and adapter pair; power output 3 watts @ 800 mhz, 2 watts @ 1900 mhz

Properties:

An electronic device whose radio frequency input signals control power from a source independent of the input signals, and delivers radio frequency output signals of greater amplitude with respect to current and/or voltage. The output signals characteristics are uniformly related to the input signals. It operates at frequencies above 20 kilohertz.
