Follow these steps to set the antenna’s linear LNB
to the correct skew angle for your selected
satellite and vessel position.
a. Using HyperTerminal or KVH Flash Update
Wizard, type SKEWANGLE then press
Enter. Note the reported skew angle.
TIP: If two satellites are installed, you might wish to
set an average skew instead. To find the average
skew, select the second satellite then repeat Step 14a to
get the second satellite’s skew angle. Add the two skew
angle numbers and divide by two to get the average.
b. Turn off and unplug the receiver(s) and
disconnect antenna power at the switchplate.
c. Remove the antenna’s radome, if you
installed it earlier in Step 7e.
d. Locate the LNB on the back of the antenna’s
reflector (see Figure 29).
e. Loosen the two wing screws on the base of
the antenna’s feed tube, located in the center
of the reflector (see Figure 30).
f. Adjust the LNB clockwise or counter-
clockwise until the skew arrow on the LNB
points to the skew angle that you noted in
Step 14a (see Figure 31). If the skew angle is
greater than +15°, subtract 180 to get the
equivalent negative skew angle and set the
LNB to that angle instead.
g. Tighten the wing screws to secure the LNB.
h. Reinstall the radome (as explained in
Steps 7e-f on page 9).
CAUTION
Disconnect power from the antenna and the
receivers before you adjust the LNB. The
antenna’s moving parts can cause injury.
