Universal Mounting Bracket for Boat Antenna and Navigation Light

Our review of the Universal Mounting Bracket finds it best suited for boat owners who need a neat, durable platform for antennas, navigation lights, or LED fixtures. The single biggest reason to buy is the large 3.5in x 3.5in flat mounting surface that turns curved t-top tubing into a usable, stable sheet for accessories. Built from 6061-T6 marine-grade aluminum and offered in powder-coated or bright-dipped finishes, this bracket is a practical, low-fuss upgrade for anyone using a 1.9in OD t-top tube.

Key Features

• Large mounting surface: The 3.5in x 3.5in flat plate provides room to mount an antenna and a navigation light or multiple small accessories at once.
• Universal fit: Designed to clamp onto 1.9in OD tubing, the bracket works on t-tops where that diameter is present and accepts top or bottom mounting positions.
• Multiple finishes: Available in powder-coated white or black and bright-dipped anodized finishes so the bracket can match common t-top styles.
• Marine-grade construction: Made from 6061-T6 aluminum for corrosion resistance and structural durability in harsh marine environments.
• Tool-free install on Fishmaster tops: On Fishmaster Original and Pro Series t-tops the bracket installs without drilling by replacing two aft stainless bolts.

Who It's For

The bracket is aimed at anglers, recreational boaters, and captains who run accessories from a t-top and want a tidy, sturdy mounting point without modifying tubing. It is especially useful for owners of Fishmaster Original and Pro Series t-tops who will appreciate the no-drill installation method.

Boaters with t-tops that do not use 1.9in OD tubing or those needing completely custom mounts should look elsewhere; drilling may be required on non-Fishmaster t-tops and the bracket is intended as a general-purpose platform rather than an integrated multi-function assembly.

Pros & Cons

Pros

• Solid 3.5in x 3.5in plate gives real space to mount multiple accessories cleanly.
• 6061-T6 aluminum construction stands up to marine exposures and resists corrosion.
• Easy installation on Fishmaster t-tops without drilling makes fitment quick and reversible.
• Finish options let owners match white, black, or anodized t-top looks.

Cons

• May require drilling or additional hardware on non-Fishmaster t-tops, so universal fit is not truly tool-free for every boat.
