STANDARD GAIN HORN ANTENNAS

Standard gain horn antennas are precision-engineered, broadband microwave antennas designed to deliver highly stable gain, predictable radiation patterns, and excellent impedance matching across wide frequency bands. Their flared waveguide structure ensures controlled directivity and low measurement uncertainty, making them a universal reference antenna for EMC, antenna calibration, microwave measurements, and radar system testing.

DIOON standard horns are manufactured with high-precision aluminum or brass, optimized for low VSWR, robust mechanical integrity, and consistent performance in both laboratory and outdoor environments.
