Fixed Wireless Terminal Description and Installation
Introduction
Check local codes for external grounding requirements.
Do not install the antenna above the rooftop.
WARNING
When an external antenna is required, first determine the general
direction of the cell site with which the FWT will communicate. This
will define which exterior wall is better exposed to the RF signals.
Figure 12 illustrates typical planning considerations concerning the
relationship between the cell site and external antenna.

A
IN THIS CONFIGURATION,
EITHER THE FRONT OF THE
HOUSE (A) OR SIDE (B) MAY BE
ADEQUATELY EXPOSED TO THE
SIGNAL. EXPERIMENT WITH
THE ANTENNA TO FIND THE
STRONGER SIGNAL.
IN THIS CONFIGURATION, THE FRONT OF THE
HOUSE (A) IS MORE DIRECTIONALLY EXPOSED
TO THE SIGNAL. HOWEVER, SIGNALS
REFLECTED OFF NEARBY STRUCTURES MAY
IN FACT PRODUCE A PREFERRED SIGNAL ON
ANOTHER WALL, ESPECIALLY IF THE RF
SIGNAL’S LINE– OF–SIGHT IS OTHERWISE
OBSTRUCTED. EXPERIMENT WITH THE
ANTENNA TO LOCATE THE STRONGER SIGNAL.
Procedure
Table 6: Installing an external antenna
n Step Action
NOTE
The FWT antenna should NOT be installed where it would be within a few
inches of a location where people normally stand, sit, or rest.
1 Connect the cable to the FWT and route the cable to the planned outdoor
location. Do not drill the hole through the outside wall at this time, rather
route the cable through an open window, if possible.
2 Two people may be required to locate the preferred signal strength; one to
experiment with the antenna outside; the other to monitor the signal strength
on the FWT indoors.
3 Connect the cable to the antenna. Refer to the signal strength testing
procedure on page 2-7 and, by moving the antenna around instead of the
FWT, monitor the LED to determine the preferred mounting location.
