FINAL ASSEMBLY OF ANTENNA AND MOUNT

Set the axis(mount boom) approximately the same degrees as your latitude (See chart). The dish is
tipped forward in the amount of the declination (from the chart) and the mount must point south.

Some things should be set and some adjusted. The following should be set and then left alone. The
dish front surface must be flat and the feed should be centered and have the proper focal length.

The declination angle should be set. There are only two adjustments to polar track, one is the
elevation (latitude) and the other is pointing south (very critical and very small movements are
involved). Have a TV by the dish to set up. You need an inclinometer to set the declination and
boom angle and also a compass to find south. Find a satellite, the closest to the south of you. Get
picture, adjust the elevation. Try a satellite East or West and if your arc does not match the polar
arc, you must move the apparatus East or West. If you go West and are under the satellite, do not

raise the elevation. Move the mount slightly west, approximately around an 1/8". The same also
applies for the East.










A WORD ABOUT KU FREQUENCY

Installing the feed for 12 Ghz is more critical than on C- Band. This is why DHhas a special fead
collar and struts just for the Ku application. (See fig. 7) The center of the feedhorn must

be exactly at the focal length (Fig.7). Also, check to be sure the feedhorn is centered by measuring
from the edge of the dish. Check to see-that. the feed is pointed directly at the center of the

dish.
