The below table shows the values for a
SAILOR 150 FleetBroadband
antenna mast without stays or
wires. Note that these values are only guidelines - always consider the environment and
characteristics of the ship before deciding on the mast dimensions.
The mast mount kit interfaces to a 1½” tube (OD 48.3 mm - absolute maximum OD 52 mm). Masts
with larger diameters must be tapered and the upper part of the tube (approximately 50 mm) must
have a diameter of 1½”.
