SAT-225-400CL: Tactical SOTM "X-Wing" Dual-Mode Antenna

The SAT-225-400CL is a high-performance, two-port SATCOM On-The-Move (SOTM) antenna designed for seamless ultra-high frequency (UHF) communication. Featuring a distinctive "X-Wing" architecture, this antenna provides dual-functionality: high-angle coverage for satellite links and low-angle coverage for standard line-of-sight (LOS) air-to-air or air-to-ground communications. Engineered for vehicular, shipboard, and tactical shelter applications, it allows for simultaneous dual-mode operation without the need for an external diplexer or switching system.

Design: Unified Satellite & Line-of-Sight Command

The SAT-225-400CL is optimized for high-mobility units that require persistent connectivity with both orbital assets and local tactical networks.

• Dual-Port Functionality: Equipped with two independent ports, allowing it to be connected to two separate radios simultaneously.
  • Port 1 (High-Angle): Optimized for SATCOM with Right-Hand Circular Polarization (RHCP) to ensure link stability with satellites.
  • Port 2 (Low-Angle): Optimized for Linear-Vertical polarization for ground-to-ground or air-to-ground Line-Of-Sight (LOS).
• Zero-Switching Architecture: The internal design provides a minimum of 22 dB isolation between the two ports. This enables simultaneous operation of both modes without requiring an external diplexer, simplifying the tactical RF chain.
• SOTM Optimized: The "X-Wing" configuration is specifically designed to maintain a high-angle radiation pattern, making it ideal for communication with satellites even when the vehicle is in motion or the satellite is low on the horizon.
• Universal Radio Compatibility: Fully compatible with tactical Multi-Band Multi-Mode Receivers (MBMMR) and standard airborne or ground transceivers.

Construction: Rugged Tactical Integration

Built for the rigors of field deployment on mobile platforms and marine vessels.

• Standardized NATO Mounting: Features a standard NATO 4-hole pattern base, allowing for rapid installation on most military vehicles, maritime platforms, and tactical shelters.
• Non-Magnetic Robustness: The non-magnetic mount design ensures no interference with vehicle navigational systems or sensitive onboard electronics.
• High-Grade Materials: Utilizing lightweight yet durable Aluminum radiating elements and Silver-Plated Brass connectors for maximum conductivity and corrosion resistance.
• Environmental Hardening: Finished in a durable Military Color coating, the antenna is rated for 180 Km/Hr winds and extreme operating temperatures from -30°C to +70°C.

Technical Features

• Dual Polarization: Combined RHCP (High-Angle) and Vertical (Low-Angle) in a single housing.
• Optimized VSWR: Port 1 features a superior 1:1.5 VSWR for efficient satellite uplinks.
• Power Capacity: Handles up to 200W (SATCOM) and 100W (LOS), supporting high-fidelity voice and data.
• Compact Footprint: Measuring only 300 mm long and 600 mm wide, it maintains a low profile on vehicular roofs.

• Port Connectors: Features an N-Female for the high-power SATCOM port and a TNC-Female for the LOS port for easy identification and secure connection.
