Installing Antennas
This section provides a procedure for installing a GPS antenna. Before beginning
the installation, review Planning the Installation, on page 278, and gather the
necessary tools and materials described in Antenna Installation Tools and Materials,
on page 281
Antenna Connection Overview
The SSU-2000 chassis has two antenna connections located on the rear panel. The
antenna connections are made via isolated TNC connectors J6 and J7, labeled
ANTENNA-A and ANTENNA-B, respectively. The connectors are DC isolated and
AC bypassed to frame ground. These connections are used for radio receiver
antenna connections only. The antenna connections (J6 and J7) are connected via
the backplane to module slots 3 and 5. When installing GPS antennas, the installed
modules must correspond to these connections (for instance, slot 3 to ANTENNA-A
and Slot 5 to ANTENNA-B). Installation procedures for GPS antennas are outlined
below. Table 5-11 outlines the antenna signal connections.
Planning the Installation
Prior to installing the antenna, you should plan the site, antenna location, grounding
scheme, cable route, and all other details.
Locating the Antenna
Use Figure 5-1 as a guide to locating the antenna.
