Description

Adjustable Marine Antenna Base — Chrome/Zinc | SED-329300-1

Mount your VHF or marine radio antenna with confidence using this Adjustable Marine Antenna Base in a durable chrome-over-zinc construction. Designed for permanent deck or rail mounting, this adjustable base allows you to fine-tune antenna angle for optimal signal transmission and reception — critical for reliable VHF communication, AIS performance, and safety at sea. The chrome/zinc finish delivers a premium, corrosion-resistant appearance that holds up in the harshest saltwater environments.

Key Features

• Adjustable angle — allows the antenna to be tilted and locked at the optimal angle for your vessel’s mounting location, compensating for deck camber, rail angle, or mast rake
• Chrome-over-zinc construction — die-cast zinc base with chrome plating delivers excellent corrosion resistance, structural rigidity, and a polished, professional finish
• Universal antenna compatibility — standard thread fitting compatible with most VHF, AIS, and marine radio antennas
• Secure deck or rail mount — robust base plate designed for permanent installation on deck, cabin top, or rail mount applications
• Low-profile design — keeps the antenna close to the mounting surface for a clean, seamless installation

Ideal For

VHF radio antennas, AIS antennas, and marine communication antennas on sailboats, powerboats, and commercial vessels where a fixed-angle mount is not suitable due to deck geometry or rail angle. An essential fitting for any new antenna installation or replacement of a worn or corroded base.

Installation Notes

• Seal all deck penetrations with a marine-grade sealant (e.g. Life-Calk or 3M 4200) to prevent water ingress
• Use a coaxial cable with the correct connector type for your antenna and VHF radio
• Ensure the base is grounded correctly if required by your antenna manufacturer
• Tighten the adjustment lock firmly after setting the desired angle to prevent movement underway
