AbstractThe electrical tests of the antenna for the production model of the counter mortar radar, AN/MPQ-501, are reported. The VSWR was satisfactory. Representatve patterns are shown. Beamwidths were 0.86° in azimuth in each beam; and in elevation, 0.84° for lower beam and 0.86° for upper beam. Side lobes are less than -20 db. Data regarding elevation beam position are presented; the beam separation is 39.6 mils at center of scan. The azimuth scan angle is proportional to rotor angle to within 0.5 mil. The gain of the antenna was 45.6 db at 16,000 mc/s at center of scan, and exceeded 45 db within the active limits of scan at all frequencies. Data with the production polarizer in place were obtained with respect to radiation patterns, gain, beam position, and axial ratio. The mean axial ratio was 0.95.
