4-Cavity TXRX 350W UHF Duplexer

$ 1,565.00
At UHF, the TX RX Vari-Notch® design is the most commonly used. Vari-Notch® provides a low-loss pseudo-bandpass characteristic that can exist very close to a deep notch. Proven low-loss and low-noise construction techniques are used such as welded cavity construction; silver-plated loops, Alballoy®-plated integrated loop plates and connectors; as well as a unique fingerstock-free high-conductivity silver-plated tuning probe. Our cavities are constructed of hardened aluminum which, unlike most copper cavities, resists denting and associated detuning.

  • All high RF-current components silver-plated for highest performance
  • Vari-Notch® design provides low loss and high isolation.

    The duplexer is still working great. The previous one was in service 30 plus years. The system was struck by lightning several times over the years and finally went south and replaced by this one.
