Shakespeare 410-R — Deck & Side Swivel Mount Kit for Large-Diameter Antennas
The Shakespeare 410-R is a heavy-duty swivel mount kit designed for large-diameter antenna shafts that standard ratchet mounts can’t accommodate. The deck or side-mount swivel base pairs with a molded upper bracket to securely hold antennas with 1", 1-1/8", or 1-1/2" diameter shafts — making it the correct mounting solution for commercial-grade and long-range VHF antennas that use a clamp-style base rather than a threaded connection. All mounting hardware is included.
Key Features
- Swivel base with molded upper bracket — secure, low-profile hold for large antenna shafts
- Compatible with antenna shaft diameters of 1", 1-1/8", and 1-1/2"
- Deck or side-mount installation — versatile positioning options
- Clamp-style mounting — no threaded connection required
- All mounting hardware included
- Durable construction for permanent marine installation
Parts Desk Insights
Best use case: The 410-R is the right mount when you’re installing a large commercial-grade or long-range VHF antenna that uses a clamp-style base rather than the standard 1"-14 threaded connection. It’s the correct choice for antennas like the Shakespeare 2110 Commercial-Grade VHF Antenna and the Phase III 18 ft VHF Antenna where shaft diameter exceeds what a standard ratchet mount handles. If your antenna uses a standard 1"-14 threaded base, you’ll want a ratchet mount instead — see the Shakespeare 4187 HD Stainless Ratchet Mount or the Shakespeare 4186U Nylon Ratchet Mount for those applications.
