Minimum distance to install near the
ships compass is 0.7 m (2.3 ft). Do not install the Halo Radar on the same beam
plane as a conventional pulse radar. A pulse radar
must be set to STBY or OFF any time the Halo
Radar is being operated.
If possible, ensure that the mounting
location provides the scanner with a
clear view all round the vessel. If installed on power boats that have a steep
planing angle, it is recommended to tilt the
scanner angle down at the front.
Considerations for roof mounting
When deciding a suitable mounting location for the Halo Radar, be aware that the vertical
radar beam extends 25° above and below horizontal for Halo20/20+ and 22° above and
below horizontal for Halo24. 50% of the power projects in a beam 12.5° above and below
horizontal for Halo 20/20+ and 11° above and below horizontal for Halo24. If the radar beam
cannot clear the roof line, this will decrease performance of the radar. Depending on the size
of the hard top of the vessel, it is recommended to elevate the antenna to allow the radar
beam to clear the roof line.

Note:
Where the mounting surface is constructed of any form of metal you must elevate the
radar so that the beam has complete clearance, as per Optimum performance section, else
performance will be severely impaired.
Determine scanner height
This is a guide to determine scanner height in relation to the furthest forward corner of the
hard top.
Measure the distance (

) from the Halo Radar to the furthest forward corner of the hard top.
