Description
OPEK AM403 - Large Stainless Steel L Bracket for UHF CB Antenna Mounting
Product Overview
The OPEK AM403 is a professional-grade large stainless steel L bracket designed for secure UHF CB antenna mounting on vehicles, buildings, and marine applications. This heavy-duty mounting bracket features robust 60mm x 60mm x 100mm construction manufactured from corrosion-resistant stainless steel, providing exceptional durability in harsh Australian conditions including coastal environments, mining sites, and extreme weather exposure. The L-bracket design enables versatile mounting configurations on vertical surfaces, railings, bullbars, roof racks, and building structures where traditional mirror or base mounts are unsuitable. The substantial dimensions accommodate heavy-duty antennas and high-gain installations requiring secure mounting support, while the stainless steel construction ensures long-term reliability without rust degradation common in zinc-plated or mild steel brackets. Ideal for serious 4x4 touring, commercial fleet vehicles, marine vessels, fixed-site installations, and industrial applications requiring permanent antenna mounting solutions.
Key Features
Heavy-Duty Stainless Steel Construction - Manufactured from corrosion-resistant stainless steel providing superior durability compared to zinc-plated or mild steel brackets, ensuring long-term reliability in coastal marine environments, mining operations, and extreme weather exposure without rust degradation.
Large Robust Dimensions - Substantial 60mm x 60mm x 100mm size provides secure mounting support for heavy-duty antennas, high-gain installations, and large-diameter masts, accommodating professional-grade antenna systems requiring robust mounting hardware.
Versatile L-Bracket Configuration - Right-angle L-bracket design enables mounting on vertical surfaces, railings, bullbars, roof racks, building walls, and structures where traditional mirror or base mounts are impractical, providing flexible installation options.
Marine-Grade Corrosion Resistance - Stainless steel construction withstands saltwater exposure, coastal humidity, and harsh marine environments without corrosion or structural degradation, making it ideal for boat installations and coastal vehicle applications.
Professional Installation Hardware - Large mounting bracket accommodates standard antenna mounts and bases with sufficient material thickness for secure bolt-through installation, preventing vibration loosening during vehicle operation or high-wind conditions.
Long-Term Durability - Stainless steel material maintains structural integrity and appearance throughout years of Australian sun exposure, temperature extremes, and harsh environmental conditions without requiring replacement or maintenance.

Installation Notes
The OPEK AM403 L bracket mounts to vertical surfaces using appropriate fasteners (not included) suited to your mounting surface material. For vehicle installations, drill mounting holes through the bracket into bullbars, roof racks, or chassis rails, securing with grade-8 bolts, washers, and nylock nuts. For building installations, use masonry anchors for brick/concrete or structural bolts for steel framework. The 100mm depth provides substantial offset from the mounting surface, accommodating antenna bases and allowing cable routing clearance. Mount the antenna base to the top horizontal surface of the L bracket using appropriate hardware matching your antenna's mounting requirements. Ensure all mounting hardware is tightened securely to prevent vibration loosening. The stainless steel construction requires no additional corrosion protection treatment. For marine installations, use marine-grade stainless steel fasteners to prevent galvanic corrosion. Verify structural integrity of mounting surface before installation to support antenna weight and wind loading.
Frequently Asked Questions
What size antennas is the AM403 suitable for?
The AM403's large 60mm x 60mm mounting surface and robust stainless steel construction accommodate heavy-duty UHF CB antennas, high-gain installations, and professional-grade antenna systems. The substantial dimensions provide secure support for antennas with larger base mounts, heavy barrel springs, and tall masts requiring stable mounting platforms.
Is stainless steel necessary for non-marine applications?
While stainless steel provides critical corrosion resistance for marine environments, it also delivers superior durability for inland applications including mining sites with corrosive dust, agricultural operations with chemical exposure, and coastal regions with salt-laden air. The long-term reliability eliminates bracket replacement costs associated with corroded zinc-plated alternatives.
Can I mount this bracket on a bullbar?
Yes, the AM403 L bracket design is ideal for bullbar mounting. The right-angle configuration allows vertical mounting against bullbar tubes or frames, with the horizontal platform providing stable antenna base mounting. Drill through the bracket into the bullbar structure and secure with appropriate grade-8 bolts for heavy-duty installations.
What mounting hardware is required?
The AM403 does not include mounting hardware, as fastener requirements vary by mounting surface. For metal surfaces, use grade-8 bolts, washers, and nylock nuts. For masonry, use appropriate anchors rated for the antenna's weight and wind loading. Use marine-grade stainless steel fasteners for marine applications to prevent galvanic corrosion.
Will this bracket support high-gain antennas like PRO7000?
Yes, the AM403's heavy-duty stainless steel construction and large mounting surface support high-gain antennas including Midland PRO7000, PRO6000, and similar professional-grade systems. The substantial 60mm x 60mm x 100mm dimensions provide adequate structural support for tall masts and heavy antenna assemblies, provided the mounting surface itself is structurally sound.
