RFI CD51-68-53 UHF 4 dB Mopole Antenna (450-520 MHz) with MBC base, 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’s end-fed transformer design ensures consistent and efficient RF performance across its operating band.
• The patented feed assembly allows precise trimming of the coaxial dielectric for optimal tuning and termination during installation.
• Its ground-plane-independent design enables flexible mounting options on a variety of surfaces without degrading performance.
• It delivers 4 dB of gain with a largely omnidirectional pattern, enhancing mobile signal coverage in all directions.
• The flexible nylon whip (CD51 Series) offers superior durability and resilience for mobile and rugged applications.
• The virtually indestructible base coil provides long-lasting, reliable performance even under harsh environmental conditions.
• This antenna allows quick and easy termination or re-termination in the field with minimal tools required.
• It is protected by Australian Patents #596830 and #656793, reflecting its advanced antenna engineering.

Application Areas:

• This antenna is ideal for vehicle-mounted UHF communication systems used by emergency services, transport fleets, and utility vehicles.
• It is well suited to applications requiring discreet, high-performance antennas with flexible mounting locations.
• It performs reliably in commercial and industrial radio communication scenarios within challenging environments.
• This ready-to-install solution includes the base and cable, catering to users who need a complete system with minimal setup.
