Product Description

QuinStar Technology series QSH and QSW narrow and wide beam scalar feed horn antennas have been designed for use in antenna applications requiring highly symmetric beam pattern, low VSWR and low sidelobes. Scalar feed horns with half-power full beam width ranging from about 10 degrees to 60 degrees are available, with standard designs at 25, 40 and 55 degrees.

These feed horns are ideally suited for illuminating lens (in Lens Horn Antennas) and as feeds for Cassegrain Reflector Antennas with virtually any f/D ratio. QuinStar’s Scalar Feed Horns offer high cross-polarization isolation (typically 30 dB).
