Shakespeare 4710 Flange Mount

The Shakespeare 4710 Flange Mount is a low-profile marine antenna mounting system designed for permanent deck and bulkhead installations on boats of all sizes. Built from stainless steel construction, this fixed flange mount provides a corrosion-resistant foundation for GPS antennas, radar systems, VHF transceivers, and marine TV antennas without the complexity of adjustable mounting hardware.

The 1.5-inch mounting height keeps the overall profile minimal, making it ideal for radar arch installations, hardtop frames, and other elevated mounting points where clearance and aesthetics matter. Stainless steel resists saltwater corrosion and UV exposure—critical for long-term reliability in harsh marine environments. The fixed flange design means no moving parts to fail, no adjustment mechanisms to seize, and no maintenance beyond basic cleaning. This simplicity translates to years of dependable service without the wear patterns common to swivel or articulating mounts.

The Shakespeare 4710 is best suited for weekend fishermen and cruisers who prioritize permanent installation over portability, as well as offshore and commercial operators running small-to-medium antenna arrays. It works particularly well for vessels with radar arches, hard tops, or other rigid superstructure where a permanent mount won't interfere with boat operations or passage under bridges and overhangs. If your antenna needs to lower for towing or seasonal storage, a fixed mount isn't the right choice—but for dedicated seafaring vessels, the Shakespeare 4710 delivers unmatched simplicity and durability.
