Mounting The Antenna Unit Of Model1834C - Furuno 1824C Installation Manual

1.3 Mounting the Antenna Unit of MODEL1834C

1.3.1 Mounting considerations
• See the mounting considerations for the MODEL1824C on page 1-4.
• Observe the compass safe distances mentioned in the SAFETY INSTRUCTIONS to
prevent deviation of the magnetic compass.
1.3.2 Mounting procedure
1. Open the antenna unit packing box carefully.
2. Unbolt the four bolts at the base of the radome cover to remove the cover.
The mounting surface must be parallel with the waterline and provided with five holes
(four fixing holes and one cable entry) whose dimensions are shown in the outline
drawing at the back of this manual.
The unit is adjusted so a target echo returned from the bow direction will be shown on
the zero degree (heading line) position on the screen. When drilling holes, be sure they
are parallel with the fore and aft line.
3. Prepare a platform (wood, steel*, or aluminum) of 5 to 10 millimeters in thickness for the
antenna unit.
A mounting bracket for mounting the antenna unit on a sailboat mast is optionally
available. (Refer to page 1-16.) Find the cable entry on the radome base. Next, position
the radome base so the cable entry faces the stern direction. This alignment must be as
accurate as possible.
*: For steel platform, take appropriate measures to prevent corrosion.
