Appendix A
Using a Surge Arrester
These instructions cover the installation of the Arbiter Systems Model AS0094500, Surge Arrester, as illus-
trated in Figure A.1. The AS0094500 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 AS0094500 is a three-terminal device with two type F connectors and one ground terminal. One of the
F connectors connects to the GNSS antenna and the other F connector to the GNSS receiver in the clock.
A screw terminal provides a point to connect an earth ground wire. Being weatherproof, the AS0094500 can
be mounted outdoors provided that the cabling and Type F connectors are sealed from the weather. The
surge arrester will also pass the voltage and current necessary to energize the GNSS antenna.
