Product Description

The RFI CD50-68-53 UHF Mopole Antenna is a high-performance, 4 dB gain antenna designed for reliable communication across the 450-520 MHz frequency range with a versatile end-fed design and patented feed assembly. The CD50/CD51 antennas provide performance with a largely omni-directional pattern when they are mounted on a vehicle gutter or similar position. This is due to the low angle of radiation inherent in the dipole antenna pattern, resulting in a typical 4.0 dB improvement in performance compared to a 3-wave whip in the center of a metal roof.

Product Features:

  • The antenna features a unique end-fed transformer design in its base to ensure consistent RF performance.
  • The patented feed assembly enables precise impedance matching through coaxial dielectric trimming.
  • The omnidirectional radiation pattern delivers up to 4 dB of gain over a conventional ¼-wave antenna.
  • The low-angle radiation design allows reliable performance when mounted in non-center roof positions.
  • The MBC coaxial base supports flexible mounting and provides a permanent, sealed connection.
  • The rugged base coil construction ensures long-term durability under harsh environmental conditions.
  • The antenna offers a choice of stainless-steel (CD50 series) or nylon (CD51 series) whips to suit different installation needs.
  • The design is protected by Australian Patents #596830 and #656793.

Application Areas:

  • This antenna is ideal for vehicle-mounted radio communication systems used by emergency services and fleet management operators.
  • It is well suited for industrial and mining vehicles that require robust UHF antenna performance in demanding environments.
  • It performs reliably in installations where center-roof mounting is not possible, such as on fenders or bull bars.
  • It accommodates custom communications setups by using the MBC base for sealed, permanent mounting configurations.

In the Box:

  • 1 x RFI CD50-68-53 UHF 4 dB Mopole Antenna
  • 1 x MBC Coaxial Base
  • Cables and Connectors (sold separately)

Mounting Arrangements:

  • CD50-xx-70 and CD51-xx-70: Mount via a threaded stud and nut assembly, allowing easy termination, tuning, and re-termination in the field.
  • CD50-xx-50 and CD51-xx-50: Mate with the MBC coaxial base, providing an internal, permanent connection in a completely sealed unit.
