2. While watching the signal strength display, adjust the
elevation adjustment nuts by turning them a few turns
clockwise and counterclockwise until you peak the signal
again.
3. When the signal is peaked, tighten the two elevation nuts.
(See Figure 43 on page 47.)
4. To be sure you have acquired the strongest possible signal,
repeat the sequence beginning at step 2 in the section,
Peaking the signal on page 38.
5. Adjust azimuth, then elevation, then azimuth again and
continue until there is no improvement in signal strength.
6. To complete the alignment process, you must tighten the
three mast clamp bolts, but tightening them can cause loss of
signal strength. Monitor the signal strength while tightening
the clamp bolts in the following sequence:
a. Tighten the top nut until the signal strength begins to
degrade, then back off until you have regained the peak
signal.
b. Tighten the bottom nut until the signal strength begins to
degrade, then back off until you have regained the peak
signal.
c. Repeat steps a and b if necessary to peak the signal.
d. If you can fully tighten the top and bottom nuts without loss
of signal, then also tighten the middle nut and go to step 7.
(Skip step e.)
e. If you cannot fully tighten the top and bottom nuts without
loss of signal, further elevation adjustment is necessary. Go
back to step 1 and begin the sequence again.
Note: You may have to pull back on the top of the antenna to
take pressure off the elevation adjustment bolt when making
adjustments.
