Poor Location:
· Steep angle of elevation prevents vessel from picking up transponder on approach.
· Shorter range inhibits performance in high sea states.
· Often surrounded by obstructions and radar-reflecting metalwork.
· Does not provide adequate cover during all vessel maneuvers.
Transponders Should be Mounted:
· At a height
no lower than 6.5 feet (2 meters) below
the vessel-mounted sensor.
· At a height
no higher than 16 feet (5 meters) above
the vessel-mounted sensor.
· On the
outside corners
of the rig or platform to minimize the amount of metallic
structure around them.
Good Location:
· Good angle of incidence.
· Lower angle of elevation allows vessel to pick up transponder on approach.
· Longer range aids performance in high sea states.
· Usually clear of obstructions and away from enclosed corners.
· Provides adequate cover during vessel maneuvers.
Transponders Should NOT be Mounted:
· On inside corners.
· Below an overhang.
· On lower service decks below a main-deck overhang.

Use the swivel bracket to point the
transponder towards the RadaScan vessel.
Mount the transponder so that its
longest sides are vertical.
The front of the transponder must have a
clear, unobstructed line-of-sight to
seaward, facing towards the RadaScan
vessel.
Secure the transponder at the top
and bottom to prevent movement in
severe weather.
