Hub Installation
!
WARNING
Before working around electrical system components, disconnect the battery cables from the battery to prevent injury or
damage to the electrical system due to an accidental short circuit.
1. Place the hub so that the antenna is at least 50.8 mm (2.00 in.) from other electronic or magnetic equipment including
Chartplotters, VHF radios, GPS receivers, and antennas.
2. Use the following dimensions to select the desired location for the hub. Mount the hub on a bulkhead or panel near the
helm where it will be protected from the elements.
IMPORTANT: Minimum panel depth must be greater than 20 mm (0.79 in.). Use a 1/8 bit to drill pilot holes for the
fasteners. Do not drill through the panel. Drawing measurements are for reference only. Do not use for a drilling
template.
