The UMC16B multi-couplers are used to distribute signals from two antennas to eight diversity receivers to minimize the amount of cabling and antennas needed in multi-channel wireless systems. The design combines high-quality ceramic filtering with low noise, high intercept point RF distribution to provide outstanding performance and flexibility. Up to eight diversity receivers or up to 16 non-diversity receivers can be utilized across the passband of each unit.The UMC16B can be powered from an external supply, 12 to 18 VDC for mobile applications or from the optional RPS4 rack power supply. Or, the UMC16B can be powered from 90 to 240 VAC for installations using the regulated power supply furnished with the unit. A locking connector on the rear panel secures the power connection.Specifications:Type: Active RF distribution system with ceramic filteringInputs: Two 50 Ohm BNC jack on rear panelThird order intercept: +27dBm at inputOutputs:Type: 16 BNC jacks on rear panel.
