PRO-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.
