Appendix A
Using a Surge Arrester
These instructions cover the installation of the Arbiter Systems Surge Arrester, as illustrated in Figure A.1.
The surge arrester performs two basic functions:
1. Provides a solid and reliable grounding point for the antenna system connected to a GNSS receiver;
2. Protects connected equipment from the damaging effects of atmospheric static electricity and induced
voltage spikes from nearby lightning strikes or other electrical events.

Description
The Model AS0094500 is a three-terminal device with two type F connectors and one ground terminal. The
type F connectors are interchangeable. One connects to the antenna and the other connects to the receiver.
A screw terminal provides a connection point for an earth ground wire. The arrester is weatherproof and
may be mounted outdoors provided that the cabling and type F connectors are sealed from the weather.
The arrester also passes dc power to energize the antenna.
