Introduction
These instructions cover the installation of the Arbiter Systems Model AS0094500, Surge Arrester/
Grounding Block. 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 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.
