RFI CD51-65-70 UHF 4 dB Mopole Antenna (380-440 MHz); Stud Mount No Cable is 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:

• The end-fed design incorporates a unique transformer in the base section to ensure stable RF performance.
• The patented feed assembly uses trimmed coaxial dielectric to provide precise impedance matching during installation.
• It is ground-plane independent, supporting flexible mounting options beyond centered metal roofs.
• This high-performance antenna features an omnidirectional radiation pattern to deliver consistent signal coverage.
• It has a field-serviceable design that allows easy termination or re-termination without specialized tools.
• The flexible nylon whip construction enhances durability in mobile or industrial environments.
• Its virtually indestructible base coil ensures long-lasting operation.
• It is protected under Australian Patents #596830 and #656793.

Application Areas:

• This antenna is ideal for fleet and emergency vehicle communication systems.
• It is suitable for mining and industrial mobile equipment that require strict mounting flexibility.
• It provides reliable omnidirectional mobile coverage for UHF radio networks.
• It is perfect for installations needing a rugged, ground-independent UHF antenna solution.
