Hybrid CombinersPRO-PHY450-4/380-470/VSWR

4-Channel Broadband Hybrid Combiner for the frequency range TETRA380 MHz & PMR/LTE 450 MHz including antenna tuner for maximum RF matching

Description

  • Can combine up to four transceivers on one common antenna where the antenna is not well 50 Ω matched
  • By tuning the RF-matching network to the antenna,  a good Tx-Tx isolation is maintained..
  • Broadband, working in all the frequency range 380-470 MHz, without compromise the Tx-Tx isolation
  • As standard the hybrid is supplied with 30 W loads.
  • Other loads for higher input power are available on request.
