CD5-225-400: High-Gain UHF Military Aero Band Coaxial Dipole Antenna
The CD5-225-400 is a professional-grade, high-gain omni-directional antenna specifically engineered for the 225–400 MHz military aviation band. Designed to provide superior performance in tactical and mission-critical environments, this coaxial dipole antenna offers a unified solution for ground-to-air and ground-to-ground communication. Its ruggedized, all-weather construction ensures high-reliability performance across the entire UHF aero band without the need for multiple antenna systems.
Design and Versatility
The CD5-225-400 features an advanced coaxial dipole design that achieves a high 5 dBi gain, significantly extending the operational range for military base stations. Enclosed in a high-strength ABS radome, the antenna is aerodynamically optimized for low wind loading and to minimize the accumulation of ice. Its sturdy, compact profile makes it highly suitable for fixed station applications, shipboard mounting, and tactical mobile deployment, providing a consistent 360-degree horizontal radiation pattern.
Precision Fabrication and Construction
Constructed from 6063T6 ultra-corrosion-resistant architectural aluminum alloy, the internal radiating elements are vertically stacked and fully welded. This specialized welding process prevents RF inter-modulation (PIM) and ensures long-term structural integrity. The antenna incorporates a sophisticated impedance matching technique to maintain a stable VSWR and constant gain across the 175 MHz bandwidth. For maximum environmental protection, the N-Female termination is located at the bottom of the mounting pipe, and all hardware is made from Marine Grade Type 316 Stainless Steel.
High-Efficiency Performance
With a consistent 5 dBi gain and a vertical beam-width of 36 degrees, the CD5-225-400 delivers precise signal projection tailored for aviation links. It is capable of handling up to 500 Watts of RF power, making it an ideal choice for high-capacity military communication hubs. The antenna is factory-tuned for "plug-and-play" operation and is supplied in a military-standard olive green finish, with custom color options available upon request to meet specific camouflage or aesthetic requirements.
