Circular LNB Replacement Instructions
Follow the instructions below to replace a
circular LNB with a new circular LNB of the
same type. LNB types are shown in Figure 1.
NOTE: If you need to replace a linear LNB instead,
refer to “Linear LNB Replacement Instructions” on
page 4.
Step 1 - Remove the Radome
Follow the steps below to remove the radome.
a. Disconnect power from the TracVision
system and any connected receivers and/or
multiswitch.
b. Remove the eight Phillips screws securing the
radome to the baseplate. Then set the radome
aside in a safe place (see Figure 2).
CAUTION
For your own safety, be sure to disconnect
power from all wired components before
performing this procedure.

Step 2 - Replace the LNB
Follow the instructions below to replace the
circular LNB.
a. If a tie-wrap is securing the LNB cables to the
LNB, cut and remove the tie-wrap (see
Figure 3).
b. Using a 7/16" open-end wrench, disconnect
the RF cables from the LNB. Then connect
them to the same connectors on the new LNB
(see Figure 3 and Figure 4).
c. Using a 5/64" hex key, loosen the two hex
screws securing the LNB to the choke feed
(see Figure 4).
NOTE: Some antennas use wing screws instead of
hex screws to secure the LNB to the choke feed.
d. Remove the LNB.
e. Insert the new LNB into the choke feed. Be
sure to fully insert the LNB into the choke
feed to ensure optimal performance.
f. Using a 5/64" hex key, tighten the two hex
screws to secure the LNB to the choke feed
(see Figure 4).
g. Reinstall the radome and restore power to the
TracVision system and any connected
receivers and/or multiswitch.
The procedure is complete!

Linear LNB Replacement Instructions
Follow the instructions below to replace a linear
LNB with a new linear LNB of the same type.
LNB types are shown in Figure 5.
NOTE: If you need to replace a circular LNB instead,
refer to “Circular LNB Replacement Instructions” on
page 2.
Step 1 - Remove the Radome
Follow the steps below to remove the radome.
a. Disconnect power from the TracVision
system and any connected receivers and/or
multiswitch.
b. Remove the eight Phillips screws securing the
radome to the baseplate. Then set the radome
aside in a safe place (see Figure 6).
CAUTION
For your own safety, be sure to disconnect
power from all wired components before
performing this procedure.

Step 2 - Replace the LNB
Follow the instructions below to replace the
linear LNB.
a. Cut and remove the tie-wrap securing the
cables to the LNB (see Figure 7).
b. Using a 7/16" open-end wrench, remove the
RF cables from the old LNB and connect them
to the same connectors on the new LNB (see
Figure 7).
c. Using a 5/64" hex key, loosen the two screws
securing the old LNB to the choke feed (see
Figure 8).
NOTE: Some antennas use wing screws instead of
hex screws to secure the LNB to the choke feed.
d. Remove the LNB.
e. Insert the new LNB into the choke feed. Be
sure to fully insert the LNB into the choke
feed to ensure optimal performance. Then
tighten the hex screws just enough to secure
the LNB in place.
f. Rotate the skew motor assembly counter-
clockwise, until the limit switch prevents
further rotation, as shown in Figure 8. This
will ensure a stable measuring surface in the
following step.
g. Using a digital level, ensure there is no more
than a 1° difference between the angle of each
measuring surface. When the LNB is position,
tighten the hex screws to secure it into place.
h. Using a supplied tie-wrap, secure the LNB
cables and skew motor cable to the LNB, as
shown in Figure 7. Be sure to leave an
adequate cable bend radius; sharp bends or
kinks in the cables can impair performance.

Step 3 - Configure the New Linear LNB
The following instructions explain how to
configure the antenna to use the new linear LNB.
a. Rotate the skew motor assembly until the
LNB’s connectors are facing approximately
straight downward. Then, using a digital
level, measure and record the angle of the
LNB, as shown in Figure 9.
b. Reconnect power to the TracVision system.
Then connect a PC to the TracVision system.
NOTE: Connection instructions vary. Refer to the
Flash Update Wizard’s Help file for connection
instructions (see Figure 10).
c. Open the Flash Update Wizard. Then turn on
the TracVision system.Wait 2 minutes for
system startup.
d. Type the following commands into the
wizard’s “Command” box. Press Enter after
each command.
HALT
DEBUGON
SKEWMTRON
ZAP
e. The antenna will restart. Wait two minutes
for system startup.
f. Type the following commands into the
wizard’s “Command box.” Press Enter after
each command.
HALT
DEBUGON
EL,0
SKEW,0
g. Using a digital level, measure and record the
angle of the LNB (see Figure 9).
NOTE: The digital level always displays positive
angles. However, the antenna skew mechanism
regards angles clockwise from vertical as negative and
counterclockwise from vertical as positive (see
Figure 11).

h. Type the following command into the
wizard’s “Command” box. Then press Enter.
=CALSKEW,XX.X
NOTE: XX.X = the LNB angle you just recorded.
NOTE: If the angle you recorded is a negative
number, be sure to use a negative (–) sign when
entering the angle. For example, if the digital level
measures 10.5°, and it is angled clockwise from
vertical, you would type =CALSKEW,–10.5.
i. Repeat Step g. Verify that the level now reads
0° (within 1°).
j. Reinstall the radome and restore power to the
TracVision system and any connected
receivers and/or multiswitch.
The procedure is complete!
