There are eight holes around the rear of the 60" ring to accept the braces. In four of these holes,
you will install the bent braces, (because of a conflict with other parts of the mount). In the other
four holes you must first install the bent tabs. See Figure #7 on previous page. The bent tab is a piece
of steel bent in the middle approximately 1 1/2" x 3" long with two 1/2" holes. You will find these in the
bolt bag. First, fasten the bent tabs with 1/2" bolts to the 60" ring; now thread one 1/2" nut about
2/3 of the way down on the 1/2" rod end of the brace. Slip the rod end through the tab and install
another 1/2" nut. Only tighten these finger tight. Now go to the edge of the dish and place the
two 1/4" x 3/4" bolts thru the dish and into the end of the brace clip and tighten with 1/4" nuts.
Next, attach the brace tube end to the brace clip using the 3/8" x 1 1/2" bolts and 3/8" nuts.
Repeat this for all eight braces on the 3.7m, 3.8m, 3.9m, 4.2m, 4.5m, and 5.0m antenna. (see note A)
Following is a list of the different back braces for the different size antennas. Check this chart
to be sure you have the right length braces. This is listed as tube length only and does not
include the bracket or the bolt in this measurement. Refer to Figure #10.
