Shakespeare 5187 Stainless Steel Ratchet Antenna Mount
The Shakespeare 5187 Stainless Steel Ratchet Mount is a durable, heavy-duty antenna mounting solution engineered for marine VHF and AM/FM antennas where strength, adjustability, and corrosion resistance are essential. Built with high-grade stainless steel, this ratchet mount provides secure support and rugged performance in harsh marine environments.
Designed for ease of use, the ratchet system allows boaters to raise, lower, and angle antennas quickly—ideal for vessels with low clearances, radar arches, or overhead obstructions. Whether you’re docking, trailering, or navigating under bridges, the Shakespeare 5187 mount delivers dependable function and smooth, reliable adjustment.
The stainless steel construction resists saltwater corrosion, rust, and wear, ensuring long-term durability on powerboats, sailboats, cruisers, and workboats alike. Compatible with many standard marine antenna bases and whip styles (mount hardware sold separately), this ratchet mount makes antenna positioning simple and secure.
Key Performance Features
-
316 Stainless Steel: Superior corrosion resistance for long-term use in saltwater environments.
-
Four-Way Action: The versatile handle allows the antenna to tilt and swivel, making it compatible with horizontal, vertical, or slanted mounting surfaces.
-
Bolt-Hole Pattern: Standard 3" x 2.25" base footprint with four 1/4" mounting holes.
-
Cable Pass-Through: Features a built-in slot for the coaxial cable to pass through the mount, protecting the wire from being pinched or crimped.
-
Quick Release: The ergonomic handle makes it easy to raise or lower the antenna in seconds without the need for tools.

Installation Pro-Tips
-
Bedding Compound: Always use a high-quality marine sealant (like 3M 4200) under the base to prevent water from intruding into your deck or cabin top.
-
Backing Plates: For 8-foot antennas, if your mounting surface is thin fiberglass, use a stainless steel or G10 backing plate underneath to distribute the load and prevent stress cracks.
-
Handle Orientation: Install the mount so the handle is easily accessible and the antenna can lay down in a clear, unobstructed path (usually toward the stern).

Note: Mounting hardware (screws/bolts) is not included. We recommend using 1/4" Type 316 Stainless Steel oval or flat-head machine screws with backing washers and nylon-insert locknuts.
Do you have the necessary fasteners for the install?
Since the 5187 doesn't include bolts, I can help you determine the correct length of 1/4" stainless steel hardware based on your deck thickness.
The Shakespeare 5187 Stainless Steel Ratchet Mount is the perfect upgrade for boat owners who want a reliable, corrosion-resistant mounting solution that simplifies antenna deployment and adjustment on board.
