should be set to zero and mechanical position of the metal Home Flag tab should be left at the 0
°
(default)
position. Any small mechanical mount error will be compensated when “Optimizing Targeting” is accomplished
to correct for small variations of up to +/- 5.0 degrees.
If the ADE is installed with the “Bow” reference of the radome oriented 45
°
to starboard the pedestal, when at
home flag position, will be pointed 45
°
CCW of the bow (at relative 315
°
as shown in Figure 2 in the Electrical
Calibration Procedure above). To compensate for this, loosen the home flag clamp, rotate the trailing edge of the
metal home flag tab
CW 45
°
and tighten the clamp bolt (use caution not to tighten too much and strip the nylon
hardware).. You will have to estimate this 45
°
rotation based on the 60
°
spacing of the hex bolt centers. Re-
initialize the antenna and verify that when at home flag position it is pointed in-line with the ships bow. Do NOT
change the Home Flag Offset value saved in the PCU, small variations will be compensated for when “Optimizing
Targeting” is accomplished.
If the ADE is installed with the “Bow” reference of the radome oriented 90
°
to port, the pedestal when at home
flag position, will be pointed 90
°
CW of the bow (at relative 090
°
as shown in Figure 3 in the Electrical Calibration
Procedure above). To compensate for this, loosen the home flag clamp, rotate the trailing edge of the metal
home flag tab
CCW 90
°
and tighten the clamp bolt (use caution not to tighten too much and strip the nylon
hardware).. You will have to estimate this 90
°
rotation based on the 60
°
spacing of the hex bolt centers. Re-
initialize the antenna and verify that when at home flag position it is pointed in-line with the ships bow. Do NOT
change the Home Flag Offset value saved in the PCU, small variations will be compensated for when “Optimizing
Targeting” is accomplished.
