The CY-225-406D is a high-gain, military-grade UHF Ground-to-Air Circular Polarized Dual Stacked Yagi Array specifically engineered for the 225–406 MHz spectrum. Designed primarily for tactical Satellite Communication (SATCOM) and aeronautical ground stations, this array utilizes Right Hand Circular Polarization (RHCP) to provide superior link stability with orbital assets and high-performance aircraft. By stacking two crossed-element Yagi antennas, the CY-225-406D delivers a formidable 13 dBic gain, making it a critical component for long-range command and control (C2) and data link applications.
Design: Strategic SATCOM & Aero Dominance
The CY-225-406D is optimized for fixed-site and tactical installations requiring high-gain directional precision.
- Targeted 225–406 MHz Bandwidth: Precision-engineered to cover the entire military UHF SATCOM and aeronautical bands. It is fully compatible with modern tactical Multi-Band Multi-Mode Receivers (MBMMR) and high-power ground transceivers.
- 13 dBic Circular Polarized Gain: Utilizing Right Hand Circular Polarization (RHCP), the array effectively eliminates "Faraday Rotation" and polarization fading, ensuring a rock-solid link with moving satellites and maneuvering aircraft.
- Dual-Stacked Architecture: By stacking two Yagi booms, the system narrows the beamwidth (28° Horizontal / 50° Vertical) to focus RF energy, providing a massive increase in effective range and a high 20 dB Front-to-Back ratio.
- High-Intensity 250W Capacity: Built for sustained transmission, the array manages up to 250 Watts of RF power, supporting secure voice, high-speed data, and satellite-uplink missions.
Construction: Ruggedized & Rotation-Ready
Built for 24/7 survivability in extreme environmental theaters.
- Aerospace-Grade Materials: Constructed from architectural 6063T6 ultra-corrosion resistant aluminum alloy. The booms and elements are finished with a protective powder coating to resist UV radiation, salt fog, and acid rain.
- Balanced Mechanical Design: The entire array is balanced at its center of gravity to minimize the load on Azimuth/Elevation rotators. A specialized aluminum cross-member and 45-degree mounting arrangement ensure optimal signal alignment.
- Marine-Grade Hardware: All assembly fasteners, screws, and brackets are made of Type 316 stainless steel, ensuring zero oxidation in coastal and high-humidity environments.
- Flexible Mounting: While designed for use with an automated rotator, the system includes a crossover mounting plate for fixed-position mast-top installation.
- Protected Termination: Features a robust N-Female connector fixed directly to the antenna dipole for a low-loss, weather-resistant coaxial feed.
Technical Features
- Unified UHF SATCOM Solution: High-gain performance across the critical 225–406 MHz window.
- Superior Axial Ratio: A 3 dB axial ratio ensures high polarization purity for satellite tracking.
- Precision Beamwidth: Narrow 28-degree horizontal beam (when horizontally stacked) for pinpoint targeting.
- Rugged Wind Survivability: Built to withstand wind speeds up to 170 Km/Hr.
- Easy Logistics: Features a manageable 1.7-meter length and balanced 15 Kg weight for tactical transport.
Environmental Tolerance: Operates reliably in extreme temperatures from -30°C to +70°C.
Design Features CY-225-406D rugged, high gain, all weather crossed elements dual stacked yagi antenna is designed for satellite communication (SATCOM) application with right hand circular polarization. When the array is mounted on the rotator (not supplied), the crossed elements array makes an angle of 45 degrees with respect to horizontal plane. A crossed member is supplied with the array for necessary mounting arrangement on a Rotator. Dual stacked circular polarized yagi array can be used with most tactical Multi-Band, Multi-Mode Receivers (MBMMR) and ground transceivers that accept 50 ohms antenna impedance.
