ABSTRACT:
A dish antenna kit has at least one reflector, one feed horn, and an alignment tool. The alignment tool has a light source and a base. The base has at least one inner cylindrical surface having a diameter slightly exceeding the outer diameter of a rim of the feed horn. The alignment tool base positions the light source axis with respect to the feed horn axis. A method of aligning the feed horn with respect to the reflector includes: placing the alignment tool on the feed horn; activating the light source; rotating the alignment tool so that a light beam advances in an arcuate path on the surface of the reflector; determining from the arcuate path the offset of the feed horn with respect to a focus point on the reflector surface; and, if the offset is not within the predetermined tolerance, adjusting the feed horn attitude.
