Under-deck-mounting the GXM 51 Antenna

The GXM 51 can be mounted under a fiberglass surface with the adhesive pads attached to the

under-deck mounting bracket. The GXM 51 will not acquire satellite signals through metal—

you can only use the under-deck mount under a fiberglass surface.

fiberglass surface where you

want to mount the GXM 51.

2. Place the adhesive pads on

the under-deck mounting

bracket.

3. Place the GXM 51 in the

under-deck mounting bracket.

4. Adhere the under-deck
