The Lincoln Experimental Terminal LET is a small transportable ground terminal for testing and evaluating space communications techniques. The requirements, design analysis, and performance data for the LET antenna and feed system are described. The 15-foot -aperture antenna has Cassegrainian optics, and a conical-horn-reflector feed exciter producing opposite-hand circularly polarized transmitting and receiving beams. The simultaneous operation of a two-channel tracking system is also discussed.
