Chapter 4. Planning Installation
CAUTION
Be sure to complete the pre-installation checklist before you begin installing the antenna. Refer to “11.1
Appendix A. Pre-Installation Checklist” on page 56
4.1 Installation Precautions
The User Terminal installation requires extreme precaution and safety measures given the installation
environment. Failure to follow the correct installation process may lead to injury of the installer and/or cause
damage to the system. To maximize the performance of the system, a thorough review of this installation
guide is strongly recommended. In addition, you should execute the installation process as it is noted in this
manual.
To ensure your own safety and convenience of installation, note the following precautions.
• Review the general safety precautions in the Safety Precautions chapter.
• Familiarize yourself with the antenna and the mounting instructions prior to climbing any roof or ladder.
• Verify that all safety measures for outdoor or rooftop installation are in place.
• Verify all requirements before beginning the actual installation to determine if the equipment and
necessary items are available and functioning properly.
• Install the grounding system for the antenna support structure, radio hardware, and surge arrestor before
connecting the cable from the equipment to the surge arrestor. This protects the system against lightning
strikes during installation.
4.2 Selecting Installation Site
Before installing the antenna system, consider the best place to position the antenna for both performance
and safety.
4.2.1 Installation Location for Antenna
The antenna should be placed in an area with no RF signal blockage. A safe mounting place and a
restricted access location should be selected.
When the antenna is transmitting, obstacles in way of the beam path will decrease the satellite signal
strength and interrupt the connection. The antenna unit should have direct line-of-sight within 59 degrees
from zenith (or above 31 degrees of elevation from local horizon at all directions) without any obstacles in
the beam path.
4.2.2 Installation Location for CNX
An ideal location for the CNX should be:
• Within 100 m (300 ft) of the antennas
• In a dry, cool, and ventilated location
• Close to a power source
