The antenna elements have a wide angle of view in the azimuth plane and a moderate angle of view in the elevation plane, and have been designed to provide repeatable, unit-to-unit, phase tracking. All units can be provided independently or as matched sets with the phase and amplitude tracking shown below.
L3Harris can also provide the Q138 Series pre-assembled into interferometer arrays with customer specified spacing. In addition, the Q138 Series can be adapted for the reception of many polarizations with the addition of L3Harris model Q156 Series of polarizer grids. These lightweight, multilayer grids are specifically designed for interface with the Q138 Series and provide slant-45 polarization.
