A mounting base and pole must be purchased in order to attach the
antenna to a roof. A dedicated base and pole may be ordered from the
master clock supplier by requesting part number
M-GPS-MTG-KIT-1.
If the
installer wishes to purchase their own parts, the pole should be capable of
attaching securely to the base and the antenna, which requires either a
1”-14” thread or a 3/4” pipe thread. The pole and base must also each
have a hollow space large enough to allow the GPS cable to pass through
both and attach to the antenna.
If the mounting base and pole are made of metal, then the user must also provide a grounding cable
for the pole. The grounding cable should be 8AWG (8.4mm²) or thicker.
If an optional surge protector is included with the master clock, then the user must provide a second
grounding cable. This cable must also be 8AWG or thicker. Failure to install this grounding cable will
prevent the surge protector from functioning correctly.
Master clocks with the optional GPS Receiver module installed will include a GPS antenna and GPS cable.
The standard cable provided is 75ft (22.9m). A dedicated, longer cable can be ordered through the master
clock supplier by requesting the following part numbers:
E-ANT-CBL-150F-1
150ft (45.7m)
E-ANT-CBL-300F-1
300ft (91.4m)
Please note that Valcom can also provide solutions for projects where a GPS cable longer than 300 feet
(91.4 meters) is required. For more information, please contact your dealer.Using a GPS cable other than
the one provided by your dealer might result in an unreliable time signal. For this reason,
using a different
GPS cable than the one provided is strongly discouraged and will void the master clock warranty and support.
