Radar antenna height implications

Antenna elevation table
The antenna elevation from the water surface determines the distance the radar beam
travels before hitting the water surface.

Elevation impact
The radar antenna should be installed in an elevated position to permit maximum target
visibility, but not higher than necessary as sea clutter increases and short range performance
is compromised with increased installation height. On smaller vessels excessive height may
also have a negative impact on vessel stability.

Mounting

Mounting guidelines
• Choose a location that will not expose the unit to conditions that exceed the
specifications, refer to the technical specification in the "Technical specifications" on page 18
• The mounting surface needs to be structurally strong, with as little vibration as possible
• Ensure that any holes cut are in a safe position and will not weaken the boat's structure
• Before cutting a hole in a panel, make sure that there are no hidden electrical wires or
other parts behind the panel
• Check that it is possible to route cables to the intended mounting location. Leave
sufficient clearance to connect all relevant cables
• Make drip and service loops for cables
Warning:
Inadequate ventilation and subsequent overheating of the unit
may cause unreliable operation and reduced service life. Exposing the unit
to conditions that exceed the specifications could invalidate your warranty,
refer to the technical specification in the
SRT LAN up-mast transceiver
Ensure that there is adequate space for the SRT LAN up-mast transceiver housing and
antenna. Securely mount the SRT LAN up-mast transceiver prior to fitting the antenna. For
dimensional drawings, refer to "Dimensional drawings" on page 21.
