Appendix D GPS Antenna Installation
The GPS antenna with an N-Type connector, is typically a 3” diameter circularly polarized antenna with an
integrated preamplifier. A +5 volt dc bias is required via the center conductor to provide dc power for the
integrated low-noise preamplifier. Two GPS antennas are used for redundancy, the system will work with
only one antenna with the signal being split to the two receivers.
Install the GPS antenna using the following recommended procedures. Where the below procedures are
different from the GPS Antenna Manufacturer Installation Procedures, the manufacturer’s procedures should
be followed.
a. Mount the GPS antenna mounting pipe mast per your site requirements. If suitable stainless steel
attachment hardware is not provided with the GPS antenna by the manufacturer, then it must be
procured locally.
b. Attach the GPS antenna/mount assembly to the top portion of the pipe mast with a stainless steel
pipe clamp and two (2) #10-32 screws.
c. Position the coaxial cable connector (male-end towards antenna) against the mast with the
connector at underside of the GPS antenna. DO NOT connect the coaxial cable to the antenna at
this time.
d. When using round member adapters, attach two cable hangers with cable supports installed to the
pipe mast; one hanger 8” – 10” below the GPS antenna and the other positioned to adequately
secure the remainder of the cable run to the pipe mast. Loosely secure cable in hangers.
e. Install the GPS antenna manufacturer-recommended weather proofing kits to the antenna and
cable interface.
f. Install grounding kits to coaxial cable per the manufacturer’s recommend procedures.
