Mast length (S1000 antenna)
The below tables show the minimum dimensions for a SAILOR XTR GX-R2 ADU (S1000)
mast with and without stays/braces. Note that the values are only guidelines - always
consider the environment and characteristics of the ship before deciding on the mast
dimensions.
Figure 2-11: Free mast length and bracing for a tall mast
Note
Make sure that there is free space below the drain tube.
Note
The tables list the values for steel masts. For aluminium masts, the
free mast length is reduced to 75% of the values for steel.
Note
Bracing and rigid masts can still not prevent vertical vibration if the
mast is attached to a deck plate that is not rigid. Make every effort to
mount the mast on a surface that is well supported by ribs. If this is
not possible, provide extra deck plate propping.
