PRO-HDAR450-3DI-BB

Ultra Compact Broadband 3 ch. UHF450 Tx/Rx Combiner System for the PMR/LTE band 410-470 MHz
Description
  • This integrated compact single tray combining solution is able to connect the Tx and Rx channels from 3 radio-repeaters into just one antenna.
  • The combiner is standard tuned broad/wide-band up to a bandwidth of 5 MHz in the both transmit and receive band.
  • It means the operator can at any time change channel frequencies in the concerned bands without any retuning of the combiner.
  • The high performance Duplex Bandpass Filter isolates any noise interference on the receiving side, occuring from the transmitters themselves or unwanted high power signals from outside.
  • Minimal 19″ rack space required – only 2HU (88.9 mm) See more in Mounting Details
  • The very compact broadband 50 W PRO-HDAR450-3DI-BB can also be delivered in 2 or 4 channel 2HU versions. Please ask for availability.
