Once you have identified a suitable antenna
mounting site, according to the guidelines
provided on
page 4 , follow these steps to drill the
mounting holes and cable access hole to prepare
the site for installation.
a. Unfold the antenna mounting template
(supplied in the Customer Welcome Kit) and
place it onto the mounting surface. Make sure
the “FWD” (forward) arrow points toward
the bow and is parallel to the vessel’s
centerline (see Figure 8). Tape in place.
NOTE: You don’t need to mount the antenna exactly
on the vessel’s centerline (the closer, the better), but
the antenna’s forward arrow must be
parallel to it.
b. Using a light hammer and center punch,
mark the locations for the four mounting
holes and cable access hole on the mounting
surface in the locations indicated on the
template.
c. Drill a 5/16" (8 mm) hole at the four
mounting hole locations you marked in Step
b. Later, you will insert four 1/4"-20 bolts
through these holes to secure the antenna to
the mounting surface.
d. Using a hole saw, drill the cable access hole in
the location you marked in Step b. Be sure to
size the hole approximately to maintain a
cable bend radius of at least 3" (75 mm). If the
hole location is in the center of the antenna
mounting hole pattern, the diameter of the
cable access hole must not exceed 3.5"
(88 mm). Smooth the edges of the hole to
protect the cables. Later, you will route the
RF cable(s) through this hole and into the
vessel.
e. Clean and dry the antenna mounting surface.
f. Peel off the paper backing from the supplied
foam seal to expose the adhesive. Then press
the foam seal down firmly onto the mounting
surface, ensuring the hole in the foam seal
aligns with the cable access hole in the
mounting surface (see Figure 9).
