Chapter 5 Antennas
Installing Antennas
Figure 5-1. Locating the GPS Antenna
Caution: To avoid damage to the GPS antenna, do not place the
antenna where high-power radio signals are beamed directly at the
unit. Such signals can damage the preamplifier of the GPS antenna.
Warning: To avoid serious injury to personnel or damage to
equipment, exercise caution when working near high voltage lines.
In particular:
Use extreme caution when installing the GPS antenna near,
under, or around high voltage lines.
Follow local building electrical codes for grounding using the
frame ground lugs on the SSU-2000 chassis.
The in-line amplifier receives 5 VDC power from the GPS radio
receiver, and is supplied on the center conductor of the LMR-400
or equivalent coaxial cable. If the application requires an in-line
amplifier, mount the amplifier/plate assembly where the transient
eliminator would normally be mounted.
Symmetricom does not recommend cutting the antenna cables
provided in the GPS Antenna Kit.
