1.3 Description 

 
This product is designed for offices, hotel rooms, small parking lots, garages or 
small buildings, helping to improve 806 ~ 866 MHz communications signal and 
coverage by extending the coverage of a base station. 
 
Outdoor antenna receives signal between 806 MHz and 821 MHz , then USHR-
800NI amplifier amplifies the signal.  After amplification, the signal is passed 
through to the indoor antennas.  Conversely, signals from handsets are amplified
