Follow these steps to connect the data, power,
and RF cables to the antenna.
a. In addition to the data and power cables, you
will need to connect two 75-ohm RF coax
cables from the antenna to the belowdecks
equipment. Use the guidelines in Figure 20 to
determine the type of RF cables required.
b. Label both ends of the two RF cables. Label
one cable “TX,” and label the other “RX.”
c. Route the data, power, and RF cables
belowdecks through the 3" (80 mm) cable
access hole. Leave an adequate service loop,
approximately 8" (20 cm) of slack, in the
cables for easy serviceability. Later, you will
connect the data and power cables to the
control unit and the RF cables to the modem.
d. Connect the data cable to the “Data” jack on
the bottom of the antenna (see Figure 21).
Hand-tighten until the connector locks in
place; do not use excessive force.
e. Connect the power cable to the “Power” jack
on the bottom of the antenna. Hand-tighten
until the connector locks in place; do not use
excessive force.
f. Connect the RF cable labeled “TX” to the
“MTx” jack on the bottom of the antenna.
Hand-tighten, then tighten with a 7/16"
wrench for 1/4 turn to ensure an electrical
and weather-proof connection.
g. Connect the RF cable labeled “RX” to the
“MRx” jack on the bottom of the antenna.
Hand-tighten, then tighten with a 7/16"
wrench for 1/4 turn.
