Minimum distance to install near the
ships compass is 0.7 m (3.3 ft).
Do not
install the Broadband Radar on the same
beam plane as a conventional pulse radar. A pulse
radar must be set to STBY or OFF any time the
Broadband Radar is being operated.
If possible ensure that the location site
provides the scanner with a clear view
all round the vessel.
Installations on power boats that have a steep
planing angle, it is recommended to tilt the scan-
ner angle down at the front. (Beam angle is 12.5°
either side of center).
Considerations for direct roof mounting
When deciding a suitable mounting location for the Broadband Radar, be aware that the verti-
cal radar beam extends to 25° either side of horizontal. With 50% of the power projecting in a
beam 12.5° off horizontal. If the radar beams cannot clear the roof line, this will decrease per-
formance of the radar. Depending on the size of the hard top of the vessel, it is recommended
not to mount directly on to the surface, instead elevate the scanner to allow the radar beams
to clear the roof line. Below are guide lines on heights above the hard top.

Broadband Radar
Above illustrates an installation with the Broadband Radar mounted directly on to a large
hard top. This installation could suff er decreased performance as the radar energy is either
refl ected or absorbed by the hard top.
Note
:
Where the mounting surface is constructed of any form of metal you must elevate
the dome so that the beam has complete clearance, else performance will be severely
impaired.
