18 GHz Double Ridge Guide Horn Antenna

The industry standard for high-gain, broadband performance in EMC emissions and immunity testing.

The SAS-571 Double Ridge Guide Horn Antenna is a lightweight, rugged, and highly efficient solution for broadband applications. Engineered by A.H. Systems, this antenna delivers a consistent directional pattern and excellent gain across a massive frequency range of 700 MHz to 18 GHz. Whether you are performing compliance testing to FCC, MIL-STD, or CISPR standards, the SAS-571 provides the precision and durability required for both laboratory and field environments.

• Ultra-Wide Bandwidth: Operates seamlessly from 700 MHz to 18 GHz, eliminating the need for multiple antennas and frequent equipment swaps.
• High Power Handling: Capable of handling up to 300 Watts of continuous power, making it an ideal choice for radiated immunity testing.
• Precision Calibration: Each antenna is individually calibrated at 1, 3, and 10 meters (horizontal polarity), with data provided to ensure immediate, accurate measurements.
• Linearly Polarized: Optimized for directional signal reception and transmission with a low VSWR for superior impedance matching.
• Rugged Construction: Built with a durable design to withstand the rigors of daily testing while remaining lightweight (only 3.5 lbs) for easy portability and mounting.
