Antenna mast design
Overview
The antenna mast must be designed to carry the weight of the antenna unit, which is
approximately 3.9 kg (+ 1.1 kg for the mast mount kit)
The mast must also be able to withstand onboard vibrations and wind forces up to 108 knots on
the radome, even in icing conditions.
Antenna mast mounting
Mast mount kit:
The top of the SAILOR 150 FleetBroadband antenna mast should be fitted with the dedicated
mounting kit available from Thrane & Thrane.
Assemble the mast mount kit according to the assembly instruction included with the kit.
The mast mount kit interfaces to a 1½” pipe (OD 48.3 mm). If the supplied plastic sleeve is omitted,
a maximum diameter OD of 52 mm can be used.
Custom mast mounting:
For a custom mast mounting, use 4 M6 bolts (A4) in the threaded bushes on the 175.4 mm
diameter circle in the bottom of the antenna. The length of the bolts must be such that they
engage into the bushes of the radome with min. 6 mm and max. 12 mm. No drainage hole is
necessary. Drill a hole for the cable or use an angled connector.
