RFI CD51-68-70 UHF 4 dB Mopole Antenna (450-520 MHz) with Stud mount and 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:

• This antenna’s end-fed transformer design provides consistent electrical performance and efficient signal radiation.
• The patented feed assembly enables precise termination by trimming the coaxial cable’s dielectric to the exact length required.
• Its ground-plane-independent design allows versatile mounting locations beyond central vehicle roofs.
• The antenna delivers 4 dB of gain with a largely omnidirectional pattern, ensuring strong and reliable communication coverage.
• The flexible nylon whip (CD51 Series) offers superior resilience in mobile and rugged applications.
• The virtually indestructible base coil ensures durability and a long service life under harsh conditions.
• The smart mechanical configuration allows convenient field termination and re-termination without specialized tools.
• This design is protected by Australian Patents #596830 and #656793, reflecting its advanced proprietary technology.

Application Areas:

• This antenna is ideal for mobile UHF radio communication in transportation, utility, and public safety fleets.
• It is well suited for rugged industrial environments such as mining, construction, and heavy vehicles.
• The antenna is compatible with UHF mobile radios operating in the 450–520 MHz frequency range.
• It is recommended for installations where space is limited but high performance is required.
