PRO-PHY450-2/380-470/VSWR

2-Channel Broadband Hybrid Combiner for the frequency range TETRA380 MHz & PMR/LTE 450 MHz including antenna tuner for maximum RF matching
Description
  • Combines two 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 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.
