Run the digital cable from the HD Digital Radome Antenna to the
signal and power connection points:
• Run the signal connector to the appropriate MFD.
• Run the power cable to a suitable 12 V or 24 V connection point
on the boat's power system. We recommend connection is made
at the boats power distribution panel, wherever possible.
Caution: Pulling cables
Do NOT use cords or ropes, attached to cable
connectors, to pull cables through restricted
apertures (e.g. as in bulkheads), as this could
cause damage to cables.
Routing cables
Cables must be routed correctly, to maximize performance and
prolong cable life.
• Do NOT bend cables excessively. Wherever possible, ensure a
minimum bend radius of 100 mm.
• Protect all cables from physical damage and exposure to heat.
Use trunking or conduit where possible. Do NOT run cables
through bilges or doorways, or close to moving or hot objects.
• Secure cables in place using tie-wraps or lacing twine. Coil any
extra cable and tie it out of the way.

• Where a cable passes through an exposed bulkhead or deckhead,
use a suitable watertight feed-through.
• Do NOT run cables near to engines or fluorescent lights.
Always route data cables as far away as possible from:
• other equipment and cables,
• high current carrying ac and dc power lines,
• antennae.
Connecting antenna
Ensuring that the arrow on the digital cable connector is aligned
with the red triangular mark on the HD Digital Radome Antenna
connector, connect the digital cable to the connector on the HD
Digital Radome Antenna, and fully hand-tighten. Do NOT use a
wrench or any other tool.
Note: If the antenna connector is disconnected after initial
installation, we recommend that before reconnecting, you lightly
coat the connector thread with Renolit Aqua 2 Calcium grease.
Connecting signal
Referring to the connection information for the multi-function display
(MFD) to which you are connecting, and to the Typical systems
diagrams given here, connect the digital cable signal connector
to the appropriate MFD.
