Antenna Mast Design

The F55/F77 value of the installation angle is defined as shown below (seen
from above ship).
Long-term, trouble free operation depends on good mast design avoiding
severe shocks and vibration levels. As every ship has unique structural
characteristics, it is difficult to give specific design rules. Nevertheless, every
attempt should be made to design a mast which has a natural frequency
>25 Hz (i.e. stiff) to avoid the majority of the ships vibration spectrum.
The table below gives some suggested design values for the free part of the
pole mast.
