2.3.2 Radome Antenna Mounting

Selecting the best location for the Scanner Unit requires careful
consideration. On many small vessels, the unit can be installed on a
mast platform, on an arch, or on bridge structure. Since radar
basically operates at line-of-sight, the unit should be mounted as high
as possible on the vessel to obtain the best long range performance.
The scanning beam should not be obstructed by surrounding large
objects. Try to locate the radome unit where other large structures or
equipment such as searchlights, horns, or masts are not in the same
horizontal plane, otherwise, blind areas and false targets can appear
on the radar screen.
Installation near the top of exhaust stacks must be avoided as damage
to the radome could result excessive heat and the corrosive effects
