Mounting the Antenna Under a Surface
NOTICE
Verify that the supplied screws will not penetrate the surface
before you install the under-deck mounting bracket. If the
supplied screws are too long, use surface-appropriate screws
instead.
Because the antenna cannot acquire signals through metal, it
must be mounted under a fiberglass surface only.

Determine and test the location under a fiberglass surface
where you want to mount the antenna (
).
2
Place the adhesive pads on the under-deck mounting
bracket .
