CD-400-1500: Ultra-Wideband Omni-Directional Coaxial Dipole Antenna
The CD-400-1500 is a professional-grade, ultra-wideband omni-directional antenna designed for seamless operation across the 400–1500 MHz frequency range. This high-performance coaxial dipole is engineered for vertical polarization, making it an ideal single-antenna solution for fixed base stations, shipboard installations, and tactical mobile applications. Its broad spectrum coverage eliminates the logistical complexity and cost of maintaining multiple narrowband antennas.
Design and Versatility
The CD-400-1500 features a rugged, all-weather design protected by a UV-resistant ABS radome. A key technical highlight is its high suppression of skin current, which ensures a smooth and stable VSWR throughout the entire 1100 MHz bandwidth. The cylindrical enclosure is aerodynamically optimized for low wind loading and to prevent the accumulation of ice, ensuring that the antenna remains operational in the most severe environmental conditions while maintaining an aesthetically pleasing, low-profile appearance.
Precision Fabrication
Constructed using 6063T6 ultra-corrosion-resistant architectural aluminum alloy, the antenna consists of vertically stacked radiating elements. The integration of a specialized "Choke and Spark Gap" technique ensures constant superior performance and electrical stability. To survive the harshest maritime or industrial settings, the antenna is supplied with Marine Grade Type 316 Stainless Steel mounting hardware. The N-Female termination is strategically fixed at the bottom of the mounting pipe, providing complete weather protection for the cable connection.
Optimized Performance
With a typical 2 dBi gain and a wide vertical beam-width of 78 degrees, the CD-400-1500 delivers excellent 360-degree horizontal coverage and stable links for mobile platforms. It is capable of handling up to 250 Watts of RF power, making it suitable for high-demand communication hubs. The antenna is factory-tuned for immediate "plug-and-play" deployment, requiring no field adjustments or tuning across its entire operating range.
