Pyramidal Standard Gain Antennas/Horns

ASY-SGH Series

Pyramidal Standard Gain Horns

Product Description

Pyramidal Standard Gain Horns (SGH) are widely used as reference gain antennas and Far-Field test range feeds, as well as linearly-polarised standards for polarisation and channel balance calibration of Near-Field probes.
A robust design allows ASYSOL SGHs to be scaled to any frequency range ( 500MHz to 60GHz in standard octave bandwidth) with reliable performance. High accuracy manufacturing enables a symmetrical radiation pattern with very low cross-polarisation, typically below -45dB.

ASYSOL SGH’s are equipped with an integrated coaxial connector and circular mounting flange , enabling them to connect with ASYSOL standard positioners. Customised models are also available, for example, with a standard waveguide flange or custom mechanical interface. The horns are treated with an Alodine surface finish and painted to ensure environmental protection.

A full measurement report is supplied with every horn, including the following parameters:
