Installation

Installation guidelines

The information provided by radar is of vital importance to skippers and the safe navigation
of ships. Special care should be taken to ensure correct installation of the radar, in order to
ensure the performance of the radar system is not compromised.
Interference, either by reflecting structures or other RF transmitters, may significantly impair
radar performance by creating blind sectors, clutter on the radar display or generation of
false targets.
The antenna should be mounted clear of any structure that may cause signal reflections and
resultant blind sectors. Large flat metallic structures perpendicular to the radar generally
cause the worst reflections, and should be avoided.
All hardware should be mounted with appropriate gauge and number of fasteners, and
structure radar is mounted to should be determined to be fit for purpose, capable of
supporting the radar in any weather or sea state.
Service platform
Safe service access should be provided using service platforms where necessary, having a
minimum size of 1 m2 at a suitable height and with a safety rail of suitable height.
The design of the mounting platform for the up-mast transceiver should take into account
the vibration requirements defined by IEC 60945.
The platform that is being mounted to should be level when vessel is loaded and underway
at typical cruise speed.
Ú Note:
When working at height, ensure appropriate safety harness and lanyard is used.

Interference

Other radars
Do not install the radar transceiver on the same beam plane as other radars, provide at least
45 degrees vertical separation. Use sector blanking as required to eliminate interference from
same frequency radar on vessel.
The following illustrations shows suggested minimum vertical separation for different radar
combinations, where radars are installed one above the other:
