An alignment jig 220 aids in the positioning of a horn assembly 180. The alignment jig 220 includes an upper jig arm 222, a right side jig arm 224, a left side jig arm 226, and a reference ring 240. The jig arms are positioned at the top, right side, and left side of an antenna dish assembly 100, and each contain a telescoping jig arm 228, 230, and 232. These telescoping jig arms of the alignment jig dramatically decrease the unexpanded size of the alignment jig, thereby increasing the portability of the alignment jig. The ends of the telescoping jig arms attach to the dish assembly through the use of screw clamps 234, 236, and 238. The reference ring 240 suspending from the intersecting point of the jig arms and is positioned and oriented so that it correspondingly mates with the horn assembly when the horn assembly has been properly positioned and oriented. A horn mount assembly 160 and a feed legs assembly 120 are adjusted until the horn assembly 180 is brought into proper alignment with the reference ring 240 of the alignment jig. This device greatly simplifies the procedure of aligning the horn assembly 180 with the dish assembly, which is usually a complicated and time-consuming task.
