AvL Model 4670HS 4.6m Tilted-Axis S-Band Tracking Antenna

AvL Model 4670HS 4.6m Tilted-Axis S-Band Tracking Antenna

The AvL Model 4670HS is a professional 4.6 m tilted-axis tracking antenna engineered for high-performance S-band telemetry, tracking, and command (TT&C) applications. Designed for aerospace, defense, government, and satellite operators, the Model 4670HS delivers continuous hemispherical tracking with exceptional pointing accuracy for LEO, MEO, GEO, launch vehicle, missile, and aircraft tracking missions.

Built around a lightweight 17-piece carbon fiber axis-symmetric reflector, the antenna incorporates AvL's zero-backlash cable drive, precision servo motors, and an innovative tilted-axis positioner that eliminates the traditional overhead keyhole effect. This enables uninterrupted satellite tracking as targets pass directly overhead, making the Model 4670HS ideal for demanding telemetry and mission-critical tracking applications.

The antenna includes a three-port circularly polarized S-band feed, embedded AvL Intelligent Terminal Controller (ITC), and fully motorized azimuth, elevation, tilt, and polarization control. Automatic satellite acquisition, cross-polarization optimization, GPS-assisted positioning, and Ethernet-based remote management simplify deployment while ensuring reliable tracking performance in harsh operating environments.
