Cabling the Modem
How the modem is cabled depends on your application. Use the guidelines in
the following subsections to assist you in cabling the modem.
Before cabling the modem, ensure that the configuration switches (described in
the previous sub-section) are set correctly for each modem.
Installing the Antenna
As shown in Figure 3-2, the antenna is connected to the rear of the modem
through the antenna connector (labeled ANT).
CAUTION When testing the radios prior to installation, do not connect the antenna connector of one
radio to the antenna connector of another radio. Doing so can cause severe damage to
the receiver.

Connecting a Low-Gain Omnidirectional Antenna
When using a high-gain omnidirectional or directional antenna, a coaxial cable
is used to connect the antenna to the modem. For more information on antenna
installation, refer to “Antenna Alignment” in this chapter and the
manufacturer’s documentation that accompanies the antenna.
