  • Combiner for coupling of four TETRA mobile transceivers on one common antenna.
  • Factory-adjusted to either 380 – 410 MHz or 400 – 430 MHz.
  • Compact dimensions – especially suitable for mobile applications.
  • FME-connectors for direct connection of FME-cable without extra adapter.
  • For parallel operation of four two-way communication radios (transceivers) where highest possible decoupling (isolation) is necessary.
  • Integrated VSWR adjustment network for optimization of isolation in the frequency range of 380 – 410 MHz or 400 – 430 MHz. Via the adjustment network the effective VSWR of the antenna can be optimized and consequently the isolation between the ports of the combiner clearly improved.
  • High isolation obtainable: Up to 60 dB (Dependent on the VSWR of the connected antenna).
  • The adjustment of the VSWR adjustment network takes place via built-in variable capacitors.
  • Max. TETRA transmitter power 4 x 5 W.
  • Also usable as equal power divider for max. 20 W.
  • Very small ripple over the total frequency range.
