The process for attaching the different squinters and taking
readings will vary slightly, depending on the reflector size
and shape.
Attaching Squinter type A
a. To attach squinter type A, place the squinter on the
elliptical feed horn so that the four guide pins on the rear of
the squinter lock securely around the feed horn rim, as
shown in Figure 9.
b. Rotate the outer piece of the squinter until the bubble in the
horizontal (azimuth) level is centered. This is the first
azimuth position. The bubble
must be at the center to
ensure that the fine adjustment is correct.
Figure 9: Attaching squinter type A
Note: You must set the squinter so that it is level, as shown
in Figure 10, rather than in line with the plane of the elliptical
feed horn. If you set the squinter in line with the feed horn,
any adjustments you make will affect both azimuth and
elevation.
