It is suitable for a variety of applications. The antenna provides a wide angle of view in the azimuth and elevation planes and has been designed to provide repeatable, unit-to-unit phase tracking. The broadband balun and terminated spiral arms provide a broad operating bandwidth with low voltage standing wave ratio (VSWR) and axial ratio.
L3Harris can also provide the Q142-1 antenna preassembled into interferometer arrays with customer-specified spacing.
