Appendix C Installing the GPS Antenna
Antenna Installation
Antenna Installation Tools and Materials
These standard tools and materials are not supplied in the antenna kit, but may be
required for installing the GPS antenna. For a list of antenna kit contents, see
Four each 0.25 in (6 mm) fasteners for installing the antenna floor flange
Extra cable ties or acceptable cable clamps
#6 AWG (minimum) copper ground wire
Eight-foot (2.9 m) ground electrode
Custom mounting plates, U-bolts, masonry bolt, and so forth, as needed for
mounting to a tower, roof, or wall of a building
A cable puller may be required for installing the antenna coaxial cable
Digital voltmeter (DVM)
Cutting Antenna Cables
Symmetricom recommends that you coil excess cable to avoid gain mismatch
between the GPS antenna and the radio receiver. Coiling the excess cable also
allows you to use the factory-installed crimped connector.
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.
Be aware of these cable and connector requirements before cutting antenna cables:
Cable Requirements
– The total cable length from the radio receiver to the
antenna must not be shorter than the minimum cable lengths indicated in the GPS
Antenna Kits
Connector Requirements
– The cables provided with the GPS Antenna Kit have
factory installed crimped connectors. If you cut these cables, you must supply and
add a connector. Symmetricom recommends that you use only crimp-style N-type
connectors in the Crimper Kit for this application.
Caution:
To prevent damage to connectors, use caution while
pulling cable.
Caution:
To avoid damage to the connectors, do not use the
connectors to pull the cable. 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.
