. Combiner
Combiners are used in applocations that require feeder sharing or co-siting. Built for both indoor and outdoor applications, normal combinations could be dual frequency combiner, three frequency combiner, this spec. is only for dual combiner (DCS&3G), this kind of combiner could combine dual inputs (DCS (1735-1860MHz) and 3G (1935-2170MHz)) into one input.
