Prepare the Antenna Site

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 the template and a light hammer and
center punch, mark the locations for the four
mounting holes.
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. Mark a location for the cable access hole, either
in the center of the antenna mounting hole
pattern or in an area aft of the antenna. Later,
you will route the antenna cable through this
hole and into the vessel.
e. Using a hole saw, drill the cable access hole in
the location you marked in Step d. 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.
f. Clean and dry the antenna mounting surface.
g. 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, centered between the antenna
mounting holes (see Figure 9).
