INTRODUCTION The test data presented in this report represents an evaluation of a 3.9m shaped Gregorian, Ka band reflector system. The tests were conducted at the SATCOM Technologies Kilgore, TX Test Range in accordance with a custom test plan of mid—band checks only. This report shows the antenna‘s performance for co—polarization side lobe suppression, on & off axis cross polarization, and antenna gain using the pattern integration method. The receive co—polarization patterns were measured in both azimuth and elevation using a synthesized CWsignal source located approximately 2.3 miles away from the antenna under test. The receive cross— polarization patterns were measured and placed under the corresponding co—polarization pattern for azimuth and elevation at multiple frequencies. (Note: Transmit cross polarization patterns were not taken due to limitations of the Long Range at the time of testing.) Antenna gain measurements were taken by the Gain by Patterns Integration method using Simpson‘s Rule calculated by SATCOM Technologies® antenna testing software package. Gain byintegration values were calculated from the antenna‘s co—polarization radiation patterns at 20.700 & 30.500 GHz. The patterns represented in this report meet or exceed specifications in RF spec 975— 2191E in accordance with acceptable measurement errors set forth in EIA—411—A.
