CPI AT-20 Series Dual Axis Directional Antenna

The AT-20 Dual Axis slotted waveguide array is designed for use in airborne and ground Tactical Common Data Link (TCDL) applications. The AT-20 features a Dual Axis Positioner and a slotted waveguide array antenna. The slotted waveguide array has antenna gain of 17 dBi at the user output connector.

The system’s brushless DC motors and servo controls have been sized to accommodate the various array configurations.

Servo controls are configured with full motion controllers which can be configured to operate in torque, velocity or position mode via serial (RS-422) or analog (+/-VDC) interface. High accuracy (16 bit) position resolution provided.

The AT-20 has the ideal performance qualities for a small ground terminal or a moderate airborne terminal with the flexibility of the slotted array and various antenna gains.
