CD-135-470: Wideband Omni-Directional Coaxial Dipole Antenna
The CD-135-470 is a rugged, professional-grade coaxial dipole antenna designed for seamless operation across the 135–470 MHz VHF/UHF spectrum. This wideband antenna provides a single-unit solution for ground-to-air, ground-to-mobile, and mobile-to-mobile communications. Its versatile mounting options, including NATO 4-hole flange and standard pole mounting, make it an ideal choice for both high-performance vehicular installations and fixed base stations.
Design and Versatility
The CD-135-470 is engineered for vertically polarized waves, delivering a consistent 360-degree horizontal radiation pattern. Enclosed in a high-strength ABS radome, the antenna is optimized for all-weather survivability, with a cylindrical profile that reduces wind loading and minimizes ice accumulation. A key technical advantage is its high suppression of skin current, which ensures a smooth VSWR and reliable electrical performance across the entire 335 MHz bandwidth, eliminating the need for multiple frequency-specific antennas.
Precision Fabrication and Construction
Constructed using 6063T6 ultra-corrosion-resistant architectural aluminum alloy, the internal radiating elements are vertically stacked to maximize signal integrity. The antenna integrates a specialized "Choke and Spark Gap" technique, ensuring constant superior performance and protection against environmental stressors. For maritime and tactical use, all mounting hardware is made from Marine Grade Type 316 Stainless Steel. The N-Female termination is strategically fixed at the bottom of the mounting pipe to provide total weather protection for the connector.
Optimized Performance
With a typical gain of 2.15 dBi and a vertical beam-width of 76 degrees, the CD-135-470 provides broad signal coverage, making it highly effective for near-field and high-angle communication. It is designed to handle a substantial 500 Watts of RF power, meeting the requirements of high-capacity communication hubs. The antenna is factory-tuned for immediate "plug-and-play" deployment and can be supplied with customized mounting configurations upon request.
