TracPhone V30 Installation Guide
Plan the Antenna Installation
Before you begin, be sure the designated install location
meets the following guidelines.
Choose a Suitable Location
• Select a location that is as close as possible to the
intersection of the vessel’s centerline and midships.
• Temperature must be within the operating range (-30ºC
to 55ºC (-22ºF to 131ºF)).
• Avoid placing the antenna near any magnetic
compasses or other onboard antennas to prevent
potential interference.
• Be sure to mount the antenna near enough to the VSAT-
Hub to allow you to connect the 50 ft (15 m) antenna
cable (supplied in kit) between them, while still
maintaining sufficient slack in the cable.
Note: If you need to use a longer cable, refer to “Prepare
the Antenna Cable” on page 9).
Mounting Structure Requirements
Make sure the mounting surface is flat, level (within ±2º),
and wide enough to accommodate the antenna’s base.
Also make sure that the structure is strong enough to
withstand the weight of the antenna (23.4 lbs, 10.6 kg), as
well as other cumulative forces related to expected
operating conditions, such as ice, snow, wash down, and
maximum expected values of pitch, roll, and wind pressure
(including gusts).
Vibration of the mounting surface should measure less
than 0.51 gRMS total, and also less than 0.11 gRMS at the
following resonant frequencies and axes:
• 23.0 Hz and 43.0 Hz in Horizontal Forward X-Direction
• 26.0 Hz and 66.0 Hz in Horizontal Side Y-Direction
• 50.0 Hz and 76.0 Hz in Vertical Z-Direction
Note: Ship’s crew should consult with the shipyard to
ensure that the antenna mounting surface vibration never
exceeds the above stated conditions at any time during its
life.
