Materials and Equipment Required for Installation
•Electric drill
•3⁄8" (10 mm) drill bit and 3" (80 mm) hole saw
•Socket wrenches
•Flat tip and Phillips screwdrivers
•RG-6 (75 ohms) cable for a second RF signal cable
(if necessary)
• Crimp tool (LRC #L3011B or e uivalent)
•Light hammer; center punch; tape; scriber/pencil
•Terminal lug crimping tool; wire strippers
•A PC with terminal emulation software such as
PROCOMM, Windows Terminal, or Windows
95/98 Hyperterminal
2-1
Installation
54-0150 Rev. E
Plan the entire installation before
proceeding! Take into account
antenna unit placement, running
cable distances between units, and
accessibility to the equipment after
installation. Cable lengths are
detailed in Table 2-2.
KVH recommends the use of
RG-6 (75 ohms) cable for RF
wiring. Use of non-RG-6
(75 ohms) cables will result in
degraded performance.The KVH
warranty does not cover degraded
performance due to improper
wiring.
Table 2-1
Installation Process

Below-decks Cable Lengths
The major considerations in locating the below-decks e uipment
are accessibility and cable lengths between units. Lengths of these
cables are as follows:
Cable (Function) Length
Data Cable (Switchplate to Antenna Unit) 50 ft (15 m)
RF Cable (Antenna to IRD) 50 ft (15 m)
Power Cable (Power to Antenna Unit) 50 ft (15 m)
IRD Ground Wire 50 ft (15 m)
2.1 Choosing the Best Location and
Getting the Best Reception
There are several factors to consider when choosing the
respective locations of the TracVision 4 antenna unit.
•The ideal antenna site has a clear view of the
horizon/satellite all around.
•Tracking errors will be reduced if the antenna
forward arrow is aligned as closely as possible
with the vessel’s centerline.
•Place the Antenna Unit as close to the intersection
of the vessel’s fore-and-aft centerline and midships.
•Keep the antenna out of line with nearby radars,
as their energy levels may overload the antenna’s
front-end circuits. If necessary, position the
Antenna Unit so it is at least four feet (1.3 meters)
above or below the level of the radar.
•Make sure that the mounting surface is rigid so
that it cannot flex when the vessel vibrates. If
necessary, add a strength member to the mounting
site to stiffen it.
2.2 Installing the Antenna Unit
Specifics of installation will vary with vessel design but the
following procedures are applicable in most situations and will
result in a secure and effective installation.
2-2
TracVision 4 Installation and Technical Manual
The radome exterior is treated
with a special finish selected for
compatibility with the dome material
and transparency to the satellite
signals. Application of additional
paints or finishes WILL degrade
performance, potentially beyond
acceptable limits.
The Antenna Unit should not be too
high off the water (a height above
the waterline no more than half the
vessel length).

Tips for Successful Antenna Unit Placement and Mounting
•The mounting surface should be essentially flat,
free of vibration and flexing, and strong enough to
carry the complete assembly (30 lbs/13.6 kg).
•The antenna unit need not be located exactly on
the vessel’s fore-and-aft axis, but its centerline
reference MUST be parallel to it.
•Be sure to account for the radome height and the
base dimensions, illustrated in Figure 2-1.
Antenna Unit Mounting Procedure
1. Using the base dimensions presented in Figure 2-1
on the following page or the template provided in
Appendix B, lay out the four mounting bolt holes.
Check the layout of the baseplate to ensure that it
is parallel with the vessel’s fore/aft axis.
2-3
Installation
54-0150 Rev. E
Table 2-3
Antenna Unit Kitpack Contents
Always lift the antenna unit by the
gray baseplate structure, not the
radome. Also be careful not to
strike the exposed connectors
extending from the bottom of the
baseplate or allow them to carry
the weight of the antenna unit.

2. Drill four 3⁄8" (10 mm) bolt holes. Mark a
3" (80 mm) diameter circle in the center of the
pattern and cut out to make a passage for the
cables to connect to the baseplate. Smooth the
edges of the hole to protect the cables.
3. Place the foam seal in position on the mounting
surface with the hole centered over the cable
access cutout and the paper backing on the
bottom. Do not remove the paper backing at this
time. Align the seal with the vessel’s fore-and-aft
line and the small end pointed forward as shown
in Figure 2-2. Scribe a line all around the seal.

A template of the baseplate
mounting holes has been provided
in Appendix B.

4. Remove and save the three screws holding the
radome to the baseplate. Carefully lift the radome
straight up until clear of the antenna assembly and
set it aside in a safe place.
5. Position the baseplate assembly in place over the
mounting holes and cable access. Ensure that all
holes line up and that the connectors are centered
over the cable access. Make any necessary
adjustments before seating the foam seal in place
permanently.
6. Clean the surface where the foam seal will be
placed. Remove the paper backing from the foam
seal to expose the contact cement. Lay the foam
seal in place, adhesive side down, and press down
firmly to bring the adhesive into full contact along
the bottom. Ensure the narrow end points toward the
bow.
7. Bring the Data Cable, RF Cable(s), and Power
Cable up through the access hole and connect
them to the baseplate. Turn the connectors down
securely, but don’t use excessive force; finger-tight
is sufficient. Figure 2-3 illustrates the connector
assignments.
Do not use teflon gel on the cable fittings as it
reduces signal strength at higher fre uencies.
8. Remove the foam shipping restraint from the
Antenna Unit.
9. Place the baseplate over the holes drilled in the
foundation, ensuring the forward arrow points
toward the bow. Rotate the azimuth mechanism
plate to expose each mounting hole. When rotating
the azimuth mechanism by hand, go slowly. Hitting the
stops with excessive force will damage the azimuth limit
switch.
10. Place a flat washer from the kitpack on a bolt and
insert the bolt into its hole from above as shown in
Figure 2-4.
11. Apply a flat washer and lock nut from underneath
as shown in Figure 2-4.
12. Tighten securely until the foam seal is compressed
as far as it will go and all four feet are bottomed
against the mounting surface.

The foam shipping restraint must
be removed before power is
applied. Save the foam for reuse
and be sure to install it whenever
the Antenna Unit is moved from
place to place. See Section 4.8,
“Preparation for Shipment,”for
instructions on preparing for
shipment.

13. For European systems, please refer to Section 2.2.1,
“Setting the Skew Angle.” North American systems
may proceed to step 14.
14. Replace the radome over the baseplate. Align the
radome screw holes with the nut holders, insert
the screws and tighten. Install a protective plastic
screw cap from the kitpack over each screw.
Several spare protective caps are provided.
2.2.1 Setting the Skew Angle (European
Systems Only)
The Antenna LNB skew angle must be adjusted to optimize
channel reception. Refer to your satellite service provider for the
proper skew angle for the selected satellite service and
geographical location.
Adjusting the LNB Skew Angle
1. Turn off the power to the Antenna Unit.
2. Remove the radome and set it aside.
3. Loosen the two wing screws securing the LNB
within the choke feed as illustrated in Figure 2-5.
4. Refer to the LNB skew angle labels on the end of
the LNB and on the LNB choke feed (pictured in
Figure 2-6) and adjust the LNB as necessary to
match as closely as possible the skew angle
provided by your service provider.
5. Retighten the wing screws.
2.3 Wiring the TracVision 4 System
A switchplate has been provided to serve as the hub of the
TracVision 4 wiring (with the exception of the RF cable, which
will be connected to the IRD). This switchplate includes an
ON/OFF switch and a DB9 maintenance port for easy access to
the Antenna Unit’s software and diagnostics.

Follow these steps to begin the wiring process:
1. Select a location to mount the TracVision 4
switchplate. It should be flat and within reach of
the cables connected to the Antenna Unit.
2. Create a panel cutout in the mounting surface.
Figure 2-7 illustrates the mounting dimensions
and a template has been provided in Appendix C.
3. Run the Antenna power and data cables from the
Antenna Unit and out through the panel cutout.
4. Run a cable from ship’s power (11-16 Vdc) through
the panel cutout.
You are now ready to wire the TracVision 4 system to the
switchplate connectors and ship’s power.
Tips for Safe and Successful Wiring
• When attaching cables to the TracVision 4
switchplate connectors, make sure the insulation is
stripped back approximately 3⁄16" (5 mm). Twist the
wires gently to help achieve a good connection. Do
not pinch insulation inside the connector.
• After attaching the power and data cables to the
appropriate terminal connector strips, tug gently
to ensure a firm connection.
