Standard GPS Antenna
The standard antenna, coaxial cable and antenna mounting
hardware come standard with GPS-referenced Masterclock
equipment packages. The GPS-based product includes the
antenna, coaxial cable with connectors, and antenna mounting.
This antenna can be mounted either indoor or outdoor so long as
it is exposed to the sky. The antenna was initially designed for
external mounting in marine environments. It is moisture proof
against most normal atmospheric conditions. If indoor it should
be mounted in or close to a window.

Antenna
Pigtail
18”/46cm long - .25"/1.3 cm diameter coaxial cable with
SMA to SMA installed.
Basic GPS Antenna
Also available is the Basic GPS Antenna. It is a
simple, magnet mounting GPS antenna with 16’
(5m) of coax cable. This antenna can be mounted
either indoor or outdoor so long as it is exposed to
the sky.

GPS receiving devices use either a TNC or SMA connector (jack) for connecting to an
external antenna. When 1/2" cable is used and is routed to the receiving device, because of the weight
and size of the cable, there could be undesirable mechanical tension or force applied to the receiver
connector. This would be particularly true in restricted areas where an adequate bending radius is not
possible for the cable. In such cases it is recommended that a "pigtail" section of coaxial cable be used to
connect from the larger cable to the receiving connector. These pigtail sections are fabricated using
Beldin 8219 cable and are shipped with appropriate connectors installed.
