Standard Gain Horn Antennas are precision-calibrated reference antennas widely used for antenna gain measurement, EMC testing, and radar system calibration. Their key advantages include:

Stable gain values (typically ±0.5dB accuracy) across designated frequency bands

Low VSWR (<1.5) and high polarization purity for reliable measurements

Repeatable radiation patterns with minimal sidelobes (<-20dB)

Rugged metal construction for long-term durability in lab/field environments

Ideal for verifying antenna performance, OTA testing, and as a gain standard in microwave applications.
