Description of DA4000SBR System
The DA4000SBR Dual Band Wireless Amplifier/Repeater system provides cellular
signal coverage to areas that have low signal strength to adequately operate a cellular
phone. In these poor coverage areas it becomes difficult to place or receive calls and
usually results in a dropped call. The DA4000SBR dual band amplifier/repeater system
provides increased reception indoors by filtering, re-directing and amplifying the
available signal. This translates into fewer dropped calls, safe, clear connections and
stronger signals. The DA4000SBR dual band system operates with all carriers in the USA
and Canada except Nextel. A
