Part 4: Antenna Pre-Set
Step 20:
Identify on the Contract Form the Elevation
(Ex: 30)
and Skew values
Step 21:
Check 4 skew nuts are loosen (fig. 11)
Step 22:
Rotate the reflector and set the Skew value
using the
marker
and the scale (fig. 12)
Step 23:
Lock off
4 skew nuts
(fig. 11)
Step 24:
Check 2 Elevation nuts
#2
&
#3
are loosen
(fig. 1)
Step 25:
Put the Elevation Offset Arrow on the
antenna (see fig. 13) and read the Offset value on
the
scale
below
(Ex: -1)
Step 26:
Add the Offset value of Step 25 to the
Elevation value of Step 20
(Ex: 30 - 1 = 29)
Step 27:
Set Elevation calculated at step 26 with
Elevation Bolt
#1
(fig. 1) using the scale and
marker
with triangular shape (fig. 13)
Step 28:
Check 2 Azimuth nuts
#5
&
#6
are loosen
(fig. 1)
Step 29:
Move Azimuth bolt
#4
(fig.1) untill the fine
azimuth scale is 0 and the upper bolt is centered
(fig. 14)
