The antenna phase center is located as follows: -Assume a coordinate system having its Z axis perpendicular to the plane defined by the top of the choke ring - with positive Z in the upward direction. The Z axis passes through the center of the 5/8" hole on the bottom of the choke ring. The origin is located at the base of the antenna dome; that it is approximately 10.16 cm. above the bottom of the choke ring base. This origin corresponds to the plane at the top of the choke ring. -The +X axis is in the direction of the arrow marked N (North) on the antenna assembly. -The Y axis is perpendicular to the X axis, with +Y defined to create a right-hand coordinate system. (Points to what would be West if the +X is pointing North.) -The phase centers are offset from this origin by the amounts show in Table 1-1. TABLE 1-1 .
