Using a line source feed illuminating a parabolic cylindrical reflector, a linearly polarized gain over 17 db is achieved. the antenna is positioned by means of a vernier type stepping motor-drive system that points the antenna beam towards earth within approximately plus minus 0.7 degree in accordance with instructions received on the satellite from the ground control station. Prior to launch, the antenna system was subjected to extensive qualification testing.
