RFI CD51-68-73 UHF 4 dB Mopole Antenna (450-520 MHz) with Stud mount, 5m cable and no connector 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:

• This antenna's end-fed transformer design ensures consistent electrical performance and efficient signal transmission.
• The patented feed assembly simplifies installation by using a trimmed coaxial cable dielectric for matched termination.
• Its ground-plane-independent structure allows versatile mounting away from central roof locations without performance loss.
• The flexible nylon whip construction enhances resilience and safety in mobile or high-impact environments.
• It delivers high-performance omnidirectional coverage with 4 dB of gain across the 450-520 MHz band.
• The virtually indestructible base coil provides long-lasting durability even under harsh conditions.
• This design is protected by Australian Patents #596830 and #656793, ensuring advanced proprietary technology.
• The stud-mounted configuration enables quick termination, re-termination, and tuning in the field.

Application Areas:

• This antenna is ideal for mobile communication systems in utility, emergency services, and transportation fleets.
• It is well suited for mining, construction, and industrial environments where durability and signal quality are essential.
• The antenna is compatible with two-way radios operating in the UHF 450-520 MHz spectrum.
• It is recommended for installations that require flexible mounting options and a robust, maintenance-free antenna solution.
