Product Description

The RFI CD50-65-73 UHF Mopole Antenna is a high-performance, 4 dB gain antenna designed for reliable communication across the 380–440 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 unique end-fed transformer design in the base ensures consistent RF performance.
  • The patented feed assembly enables precise impedance matching through coaxial dielectric trimming.
  • The omnidirectional radiation pattern provides up to 4 dB of gain over a conventional ¼-wave antenna.
  • It performs reliably in non-centre roof mounting positions thanks to its low-angle radiation design.
  • The MBC coaxial base supports flexible mounting and delivers a permanent, sealed connection.
  • Its rugged base coil construction ensures long-term durability under harsh environmental conditions.
  • It offers whip options in stainless steel (CD50 series) or nylon (CD51 series) to suit different installation needs.
  • It is protected by Australian Patents #596830 and #656793.

Application Areas:

  • These antennas are ideal for vehicle-mounted radio communication systems used by emergency services and fleet management operators.
  • They are suited for industrial and mining vehicles requiring robust UHF antenna performance.
  • They perform reliably in installations where centre-roof mounting is not possible, such as on fenders or bull bars.
  • They accommodate custom communications setups using the MBC base for sealed, permanent mounting configurations.

In the Box:

  • 1 x RFI CD50-65-73 UHF 4 dB Mopole Antenna
  • 1 x Stud Mount
  • 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.
