Digital Yacht CX4A Horizontal Deck Antenna Base

The Digital Yacht CX4A Horizontal Deck Antenna Base is made for mounting a compatible CX4A antenna on a flat deck surface. Its purpose is straightforward: provide a dedicated mounting point that keeps the antenna base secure and properly supported. The horizontal format suits installations where a vertical bulkhead or rail mount is not the right choice. It is a useful replacement part when an existing CX4A installation needs new mounting hardware or a fresh deck base.

The base is supplied with fixing bolts, so the installer does not have to source the primary fasteners separately. A gasket is included to sit between the base and the deck surface. The compact assembly keeps the installation simple while preserving a purpose-built fit for the CX4A antenna. That gasket helps create a cleaner installation at the mounting point and reduces the need to improvise a separate interface material.

Choose a flat location with enough clearance for the antenna and for any cable routing required below or beside the deck. Dry-fit the base and gasket before drilling so the bolt pattern and antenna orientation can be checked from both sides of the mounting surface. After installation, inspect the fasteners periodically as part of normal antenna maintenance. For related mounts, cables, and antenna hardware, browse Marine Antennas.
