Product Description

RFI CD51-65-73 UHF 4 dB Mopole Antenna (380-440 MHz) with Stud mount, 5m cable and no connector is a versatile and popular antenna 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:

  • This antenna uses a patented feed system that requires trimming the coaxial cable’s dielectric to a set length for precise impedance matching.
  • Its ground-plane-independent design enables flexible installation locations beyond vehicle roof centers.
  • It delivers largely omnidirectional coverage with high performance even when not center-roof mounted.
  • Its patented design allows quick and easy re-termination in the field without specialized tools.
  • The flexible nylon whip construction provides durability and resilience in harsh conditions.
  • The virtually indestructible base coil ensures reliable long-term operation in mobile or industrial environments.
  • The proprietary transformer design enhances RF stability and maintains consistent gain.
  • This antenna is protected under Australian Patents #596830 and #656793 for its innovative technology.

Application Areas:

  • This antenna is ideal for emergency services and commercial fleet communication systems.
  • It is well suited for utility and infrastructure vehicles operating across UHF bands.
  • It performs reliably in industrial and mining environments that demand rugged antenna performance.
  • It excels in installations where a stud-mounted, flexible, ground-plane-independent antenna is essential.

In the Box:

  • 1 x RFI CD51-65-73 UHF 4 dB Mopole Antenna
  • 1 x 5-meter cable (no connector)
  • 1 x Stud mount assembly (pre-installed)

Mounting Arrangements:

  • CD50-xx-73 and CD51-xx-73: Mount via a threaded stud and nut assembly, allowing easy termination, tuning, and re-termination in the field.
  • CD50-xx-53 and CD51-xx-53: Mate with the MBC coaxial base, providing an internal, permanent connection in a completely sealed unit.
