How to install the SC-703 Antenna Unit

Note 1: Where the installation location is inconvenient for cable connection, connect
the cabling (see step 6) before securing the antenna unit to the mounting location.
Note 2: The bird-repellent fixtures 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 fix-
tures before securing the antenna unit to the mounting location, do step 7 of the pro-
cedure below before fixing the antenna unit.
1. Prepare a mounting platform in accordance with the outline drawing at the back
of this manual. If corrosive material is used, take necessary anti-corrosion mea-
sures.
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 below. The antenna
should be installed within ±2.5° of the bowline.
Note: The antenna cable must be routed via the indent at the rear of the base (see
the following figure).
