8. INSTALLATION
8-5
Mounting procedure
Note 1:
The bird-repellent fixtures (optional supply) can be attached to the antenna
cover to prevent birds from landing on the cover. If it is more convenient to attach the
bird-repellent fixtures before securing the antenna unit to the mounting location, do
step 6 below before fixing the antenna unit.
Note 2:
Depending on the installation location, connecting the antenna pig tale con-
nector to a cable from the junction box in advance can make the installation easier. To
connect the cable and waterproof the connection, see step 5 of the following proce-
dure.
1. As shown in the figure below, weld a platform (local supply) for which to mount the
sensor.
If corrosive material is used, take necessary anti-corrosion measures. The thick-
ness of the platform should be 5 mm to 15 mm.
Note:
Holes drilled into the mounting platform must be parallel with the fore-aft
line of the vessel.
2. Orient the antenna unit to face the bow, referring to the figure above. The antenna
should be installed within ±2.5° of the bowline.
Note 1:
The antenna cable must be routed via the indent at the rear of the base
(see the above figure).
Note 2:
Take care not to cover the vent hole on the antenna.
3. Secure the unit to the platform with four sets of M10 hex. nuts, spring washers and
flat washers (all included as installation materials) with 20 ±2 N•m torque.
Note:
Take care not to crush the cabling when mounting the antenna to the plat-
form.
