The Antenna Cabling System

The Outdoor Cabling Components

ELECTRICAL HAZARD WARNINGS

1. Outdoor antennas and antenna cables are electrical conductors. Transients or electrostatic discharges that may occur at the antenna (e.g., lightning) may damage your electronic equipment and cause personal injury or death to persons touching the exposed metal connectors of the antenna cable.

2.To avoid damage and personal injury, the entire antenna cabling system must be grounded at all times.

3.When installing, disconnecting or replacing one of the cabling components, you must ensure at all times that each exposed metal connector of the antenna cabling system is grounded locally during the work. For example when mounting or replacing the RoamAbout Lightning Protector:

Connect each of the low-loss antenna cable connectors to the grounding system.

Connect the RoamAbout 50-cm Cable Assembly connector to the grounding system.

Connect the RoamAbout Lightning Protector to the grounding system.

4.Before you proceed, verify that each component is properly grounded and that the ground is not interrupted when disconnecting any one of the antenna system components.

5.Check with a qualified electrician if you are in doubt as to whether the lightning protector and cable connectors are properly grounded.

6.Only after verifying that each item is properly grounded, replace the lightning protector and reconnect the cables in reverse order.
