User's Manual Part 9

Elevation and Azimuth Adjustment.
Normally several alternating adjustments in eleva-
tion and azimuth will be required to achieve optimum trans-
mission path alignment. Begin by adjusting the antenna in
elevation using the concave faced nuts on the elevation
eyebolt until the antenna is as close as possible to its final
transmission path direction. Correct any azimuth mis-align-
ment by adjusting the azimuth adjusting strut. Repeat the
sequence as necessary.
Once alignment is achieved, carefully tighten all mount and
strut hardware, taking care not to disturb the antenna posi-
tioning. The following hardware tightening sequence is rec-
ommended.
4. Fully tighten bolt attaching elevation eyebolt to eleva-
tion hinge bracket.
5. Fully tighten the bolt passing through the azimuth 'U'-
bracket and strut.
6. Fully tighten bolt attaching fixed strut to mounting ring
(if applicable).
7. Tighten the strut clamp assembly of the azimuth strut
and then the clamp assembly of the fixed strut (if
required). Do this by first loosening the jam nuts. Next
tighten the setscrews until they touch the strut. Then
tighten them 1¼ turns more so that their cup points cut
into the strut. Tighten the locknuts against the bracket.
8. Fully tighten the nuts securing the clamp assemblies
to the tower members.
9. Finally re-check that all hardware has been tight-
ened.
