SECTION TWO: Installing and wiring the radar
NOTE:
1. Referring to Figure 5 below and the supplied full-size antenna mounting templates, drill four
1/2 in. (13mm) diameter holes through the mounting surface.
2. Check that each bolt (with lock washer and flat washer) protrudes at least 5/15 in. (8mm) but
less than 9/16 in. (15mm). The scanner will be damaged if bolts protrude more than 9/16 in.
(15 mm).
3. Apply sealant around each mounting hole.
4. Place the radome scanner unit on the mounting surface. Orient the radome with the index
mark on the housing facing forward (cable gland facing aft).
5. Install and tighten four M10 X 25U (M10 X 1 in.) mounting bolts
6. Secure the cable near the scanner to support the weight of the cable and prevent strain on
the watertight cable seal.
The bolts supplied will suffice for mounting base thicknesses of 3/16 to 3/8 inch (5 to 10 mm). If the
mounting base is thicker or thinner than that, use bolts specified in Table 2 on page 7. See Figure 6
below for details on bolting the antenna to the mounting base.
