From the opposite side of the reflector bracket, place a hex flange nut on each
bolt and tighten the nuts lightly, only until snug. The reflector bracket should

When the reflector bracket is correctly attached to the Az/El mount, you can
see the tilt scale numbers above the tilt pointer, as shown in
page 28. In the figure, the tilt is set to
0
.
The Az/El tilt scale can place the tilt or rotation of the antenna to either a
positive or negative position, based on coordinates, and must be set on each
installation according to specifications.
