GPS Antenna and Cable Information
The Model 1092A/B/C and 1093A/B/C come complete with the necessary hardware to be able
to receive GPS signals: 50-feet of RG-6 cable and a GPS antenna. Longer cables are available.
The antenna cable is connected between the female F connector on the antenna and the female F
connector at the rear panel of the clock.
This section should help you with installing the GPS antenna and antenna cable(s) and acces-
sories. It should also be a source of information if you should need to trouble shoot the antenna
cable system.
4.1
GPS Antenna Installation
To properly receive GPS signals, the GPS antenna needs to be mounted clear of buildings and
surrounding elements that may block the GPS signals being transmitted by the satellites. For
complete coverage, the antenna needs to have a clear view of the sky from 10 degrees above the
horizon to directly overhead for all points of the compass. Minimal installations, where the antenna
is mounted in a less favorable location, may work however reception may be somewhat limited
during certain hours of the day.
4.1.1
Mounting the Antenna
The standard antenna is designed for pole mounting on a 26-mm pole (1.05-in. OD or 3/4-in. ID
pipe), with either a standard 1-in. – 14 (approximately M25.4 x 1.81) marine-mount thread or a
3/4-in. NPT pipe thread. The Type F connector on the inside of the antenna is protected from
direct exposure to the elements when the antenna is mounted in this way. This will extend the
operational life of the antenna-to-cable interface.
To mount the antenna, you will need a short piece of gray, 3/4–in. plastic pipe nipple that can
be attached to a solid fixture. The piece of pipe nipple should be threaded up into the antenna
receptacle after connecting the antenna cable to the Type F cable adapter. Arbiter Systems sells
an antenna mounting kit (P/N AS0044600) that simplifies installation for a variety of locations.
Figures 4.1, 4.2 and 4.3 illustrate several components for a suggested mounting method.
