Shakespeare 4190 Ratchet Rail Mount Medium - Quick Install Clamp

In this review the Shakespeare 4190 Ratchet Rail Mount Medium is presented for boat owners and installers who need a sturdy, easy-to-adjust antenna clamp. The bottom line: it is ideal for mounting VHF or similar marine antennas up to 8 ft on 7/8 in or 1 in vertical or horizontal rails because of its simple ratchet action and durable cast construction. Installation is straightforward and the special cable slot saves time by avoiding removal of most factory-installed connectors.

Key Features

• Ratchet action: The ratchet system locks the antenna at any angle, making fine adjustment quick and repeatable without tools.
• Rail compatibility: Designed for both 7/8 in and 1 in vertical or horizontal rails, it fits common boat rail sizes for flexible placement.
• Capacity: Handles antennas up to 8 ft, so it works with a broad range of VHF and similar marine antennas.
• Cable slot: The special cable slot eliminates removal of most factory-installed connectors, saving time during installation and reducing risk to cables.
• Standard thread: Uses the standard 1 in-14 male thread for compatibility with most marine antenna bases and accessories.

Who It's For

This mount suits boat owners, marine electronics installers, and anyone who wants a durable, no-fuss way to secure a marine antenna to common rail tubing. Its ease of installation and ratchet adjustment make it a good choice for those who reposition antennas for reception or stowage.

Those who need to mount antennas larger than 8 ft or who have nonstandard rail diameters outside 7/8 in and 1 in should consider alternative mounting systems engineered for larger loads or custom fittings.
