TracNet H30 Installation Guide
Prepare the Antenna Cable
Prepare the Antenna Cable
You need to connect a single coax cable from the antenna
to the BDU. KVH recommends using the supplied 50 ft
(15 m) RG-58 cable. However, you may purchase a
different cable for a longer run (see Figure 9 to determine
type of cable and connectors required), or you may use a
different cable of an acceptable type and length, as
specified in
“Approved Cable Types” on page 33 or the
Cable Specs Wizard at www.kvh.com/TracNetcables . If
you wish to reuse an existing cable from a previously
installed antenna, it must be clean, free of rust or
corrosion, and meet KVH specs for type and length.
The cable run must meet the following requirements:
• A low-quality, poorly terminated, or improperly installed
cable is the most common cause of system problems.
If the cable is modified for any reason, it must be
terminated again with new connectors, using the
proper tools, exactly to the manufacturer’s
specifications. See
“Terminating RG-58 Cable” on
page 29 for instructions for the supplied cable. Only
KVH-authorized marine technicians should modify
the antenna cable, if necessary.
• Use of any cable type not approved by KVH will void
the warranty.
• Make sure the center conductor pin at each end of the
finished cable is free of burrs, as well as the correct
length and diameter specified in Figure 9, to ensure
proper engagement.
• Make sure there is no gap between the end of the cable
jacket and the start of the connector.
• When determining cable lengths, don’t forget to
account for service loops, 14" (36 cm) in diameter, at
each end, and ensure you can maintain the minimum
bend radius (which differs per cable) throughout the
cable run.
• If you do not use an RG-58 or LMR-240 cable, you
need to connect a pigtail cable between it and the
BDU. You may also use a pigtail cable at the antenna
end to maintain proper bend radius. These pigtail
cables are available from KVH. See
“Connecting Pigtail
Cables to the Antenna Cable” on page 32 .
Note: Cables purchased from KVH include the proper
connectors.

IMPORTANT!
The integrity and reliability of the antenna cable is
critically important. Make sure it is properly terminated,
sealed against seawater and corrosion, strain-relieved,
protected from abrasion, and free of stress.
