Appendix C:
Installation
Requirements
Ixia GPS equipped systems used to provide local Stratum 1 timing signals
requires the installation of a GPS antenna kit (942-0003 or 942-0005, where the
facility or environment prevent the window mount antenna from functioning).
This section describes the installation method we recommend for an IXIA GPS
Antenna. This section also provides a scheme for installation of lightning
protection for an installed antenna. In order to ensure that all of the following
criteria in this manual can be met, we recommend a site survey.
Note: This is not an installation manual and should not be used in place of
building codes for electronic installations applicable to specific sites.
This appendix has the following sections:
•
Roof Mount Antenna
•
Window Mount Antenna
Roof Mount Antenna
The general location requirements for installation of the GPS antenna and
conduit are:
Table C-1.

GPS Location Requirements

1.
Ideally, a roof area with an unobstructed 360-degree view of the sky
above the horizon. At the minimum, a 180-degree view of the sky is
required.
2.
Mounted away from and above a plane from items such as elevators,
air conditions and other machinery.
3.
Should have the best view of the horizon that is possible. No
obstructions should be within a ten-degree angle from the horizontal.
4.
There should be adequate space available on the roof to install two
antennas with an absolute minimum of 10 feet between antennas.
5.
The antenna should be 12 feet away from metallic objects.

  • Page 3 Roof Mount Antenna Conduit We recommend the coax from the GPS antenna to the Ixia unit to be installed in a secure conduit from the point directly above the chassis to the GPS antenna. The conduit serves two purposes: It protects the coax cable.
  • Page 4 No high-power radar signal beamed directly at the unit; this may damage the pre-amplifier in the antenna. No harmonics from a high-power, broad band transmitter within a few megahertz of the carrier frequency (1.575 GHz) should be present. This may jam the GPS receiver. <Italic>IxN2X Getting Started Guide, Release 7.50...
