    Example: If the SSU2000 has a GPS module installed and the module is locked with satellites, it then has UTC time. The SSU-2000 is automatically an NTP SERVER at Stratum Level 1. When the system (with GPS module installed and UTC time) is a SERVER, it cannot operate as a client.

    281 Antenna Connection Overview The SSU-2000 chassis has two antenna connections located on the rear panel. The antenna connections are made via isolated TNC connectors J6 and J7, labeled ANTENNA-A and ANTENNA-B, respectively. The connectors are DC isolated and AC bypassed to frame ground.

  • Page 280 Chapter 5 Antennas Installing Antennas Recommendation: Symmetricom recommends that you consider the following location and environment influences before installing the GPS antenna: If possible, provide the antenna with an unobstructed 360-degree view of the sky from the horizon. In general, do not allow obstructions that obscure the horizon (as...

    Connect transient eliminators, if part of the grounding scheme, to earth ground through a conductor. Symmetricom makes no recommendation as to whether to install transient eliminators.

Symmetricom does not recommend cutting the antenna cables provided in the GPS Antenna Kits. If you must cut the cables, please ensure that the following requirements are met.

  • Page 283: Connecting The Cable To The Antenna

    If at all possible, avoid bundling the coaxial cable with other cables (and possible noise sources). Use appropriate cable-pulling devices when pulling the coaxial cable through conduit or a weather head. 12713020-003-2 Revision F.01 – January 2007 SSU-2000 Technical Reference 283...

    4. Connect the ground wire between the transient eliminator and the proper grounding zone (building ground, master ground bar, or other) for the mounting location. Recommendation: Symmetricom does not recommend soldered connections for grounding purposes. All grounding connections should be secured with mechanical clamp connectors.

  • Page 285: Installing The Antenna Cable

    2. Secure the free end of the antenna cable to the appropriate antenna connector on the rear panel of the SSU-2000 using the right angle adapter provided with the antenna cable. Recommendation: Symmetricom recommends coiling excess cable to avoid gain mismatch between the GPS antenna and the SSU-2000.
