Receiver MulticouplersPRO-MARHP

Miniature Receiver Multicoupler series for the 4 m, 3 m and 2 m bands, 68 - 240 MHz

Description

Active wideband receiver multicoupler for the 4 m LMR band, the FM radio band, the VHF air band, the 2 m LMR band and the DAB radio band.
Covers 68 MHz - 240 MHz.
Allows a number of receivers to share the same antenna without interaction and loss of signal.
Models with 2 outputs or 4 outputs available.
High dynamic range amplifier built in to compensate for loss in multicoupler network.
Can simultaneously act as a low-noise preamplifier with up to min. 8 dB gain (adjustable).
Very low amplifier noise figure ensures lowest possible S/N deterioration of received and distributed RF signals.
Excellent amplifier large signal behaviour ensures handling of strong RF signals with very low level of IM and harmonic distortion.
Adjustable gain.
Power splitter with high isolation between receiver outputs.
Low power consumption.
Models for 12 VDC or 24 VDC nominal supply voltage available (please see ordering designations).
DC supply on solder terminal or on 2.5mm barrel DC connector.
RF connectors: N(f) on all ports (other types on request).
Low weight.
Wide temperature range.
Sturdy aluminium box.
Black vinyl coated to prevent corrosion.
