CD-470-860: Multi-Band Omni-Directional Coaxial Dipole Antenna
The CD-470-860 is a ruggedized, multi-band omni-directional antenna designed for high-performance transmitting and receiving within the 470–860 MHz UHF spectrum. This coaxial dipole antenna serves as a versatile, single-unit solution for fixed base stations, shipboard installations, and mobile tactical platforms. Its wide bandwidth and sturdy construction eliminate the logistical need for maintaining multiple narrowband antennas.
Design and Versatility
The CD-470-860 is engineered for extreme weather survivability, featuring a UV-resistant ABS radome that protects the internal radiating elements. Its cylindrical enclosure is specifically designed to minimize wind loading and ice accumulation, ensuring stable operation in high-wind environments. The compact 0.40-meter profile makes it an ideal choice for space-constrained applications, such as vehicle mounting or dense shipboard masts, while maintaining an aesthetically pleasing and low-profile appearance.
Precision Fabrication
Fabricated using 6063T6 ultra-corrosion-resistant architectural aluminum alloy, the antenna features vertically stacked radiating elements for consistent performance. A specialized "Choke and Spark Gap" technique is integrated into the construction to ensure a smooth VSWR and constant gain across the entire frequency range. To prevent environmental degradation, the antenna is supplied with marine-grade stainless steel mounting hardware and finished in olive green. The N-Female termination is located at the bottom of the mounting pipe for ultimate weather shielding.
Optimized Performance
Delivering a stable 3 dBi gain and a broad vertical beam-width of 78 degrees, the CD-470-860 provides excellent "null-fill" coverage, making it highly effective for near-field and high-angle communication. With a significant RF power handling capacity of 500 Watts, it is capable of supporting high-intensity broadcast and data transmission requirements. The antenna is factory-tuned for immediate deployment, requiring no field adjustments or complex tuning procedures.
