Follow these steps to connect the RF and power/
data cables to the antenna.
NOTE:
An optional 150 ft (45 m) power/data cable is
available from KVH (KVH part no. 32-1031-0150).
Route the Cables Belowdecks
a.
Route the power/data and RF cables
belowdecks through the 3.75" (95 mm) cable
access hole. Leave an adequate service loop,
approximately 8" (20 cm) of slack, at the
antenna location for easy serviceability.
b.
Route the other end of the cables to the
belowdecks equipment. Be sure to always
maintain the minimum bend radius in the RF
cables (see Figure 19). Later, you will connect
the power/data cable to the CommBox-ACU
and the RF cables to the modem.
Connect the Customer’s RF Cables to the
Supplied Pigtail Cables
a.
Clean and dry the RF cables’ connectors.
b.
Heat shrink is supplied with each 3 ft (90 cm)
pigtail cable to protect the connection
between the customer’s RF cables and the
pigtail cables. Slide a heat shrink sleeve onto
the end of each 3 ft (90 cm) pigtail cable
(opposite the boot end) for later use.
c.
Fill half of the inner body of the customer’s
“TX” RF cable’s connector with the supplied
silicone grease to prevent moisture and
corrosion.
d.
Connect and
SLOWLY
hand-tighten the
“TX” RF cable to the feed-thru adapter of one
of the supplied LMR-400-75 pigtail cables,
allowing the grease to diffuse and settle into
the entire space within the connector (see
Figure 19: Minimum Bend Radius of RF Cables

Do not connect the customer’s RF
cables directly to the antenna.
