Grounding System
3-4 Antenna Installation
Grounding System
Direct earth grounding of the antenna and the Lightning Protector is necessary to protect
the installation from lightning and the build-up of static electricity.
The grounding system must satisfy the following requirements:
• The antenna mast, RoamAbout Access Point, and RoamAbout Lightning Protector
must be connected to the same ground.
• The antenna and the mounting structure require a separate earth ground connection.
Check with a certified antenna installer to make sure the antenna is properly grounded.
• Ensure that the cable between the antenna and Lightning Protector is at least 0.9 meters
(3 feet) away from high-voltage or high-current cable.
• A good electrical connection must be made to one or more ground rods, using at least
a 10AWG ground wire and noncorrosive hardware.
• The grounding system must comply with electrical codes and safety standards that
apply in your locality.
Have a qualified electrician verify that your RoamAbout outdoor installation is properly
grounded.
Lightning Protector Installation
Lightning protection is designed to protect people, property and equipment by providing a
path to the ground whenever lightning strikes your antenna installation. The RoamAbout
Lightning Protector is an indispensable part of such a grounding system to protect your
electronic equipment from transients and/or electrostatic discharges at the antenna.
For optimal protection, the location of the RoamAbout Lightning Protector:
• Must be as close as possible to the point where the antenna cable enters the building.
• Allow for easy access to the Lightning Protector so that the Gas Discharge Tube
(GDT) in the Lightning Protector can be replaced as necessary.
• Provide a connection to the same grounding system as the RoamAbout Access Point
and the antenna mast as described in the “Verify Component Connector Polarity”
section on page 3-2.
CAUTION: A properly installed safety grounding system is necessary to
protect your RoamAbout outdoor installation from lightning strikes and
static electricity build-up.
