Description
OPEK AM903 - Marine 4-Way Deck Mount for UHF Antenna with Stainless Steel Hardware
Product Overview
The OPEK AM903 is a professional-grade marine 4-way deck mount designed for secure UHF antenna installation on boats, vessels, and marine applications. This heavy-duty deck mount features robust construction with included marine-grade stainless steel mounting hardware, engineered to withstand harsh saltwater environments, coastal humidity, and continuous marine exposure. The 4-way mounting configuration provides versatile installation options on boat decks, hardtops, bimini frames, and cabin roofs with adjustable positioning for optimal antenna orientation. Compatible with standard 1-inch x 14 TPI (threads per inch) antenna mounts, the AM903 accommodates most UHF CB antennas and marine communication systems requiring deck-mounted installation. The marine-grade design ensures long-term reliability in demanding offshore conditions including wave impacts, salt spray, and extreme weather exposure. Ideal for fishing vessels, recreational boats, commercial marine operations, and coastal applications requiring permanent antenna mounting solutions with corrosion-resistant construction.
Key Features
Marine-Grade 4-Way Deck Mount - Versatile 4-way mounting base enables installation on horizontal deck surfaces, cabin roofs, hardtops, and bimini frames with adjustable positioning for optimal antenna orientation without requiring multiple bracket types.
Stainless Steel Hardware Included - Complete set of marine-grade stainless steel mounting bolts, washers, and nuts included in package, ensuring corrosion-resistant installation without requiring separate fastener purchases for immediate marine deployment.
Standard 1" x 14 Thread Compatibility - Universal 1-inch x 14 TPI thread standard accommodates most UHF CB antennas, marine communication systems, and standard antenna mounts, providing broad compatibility with existing antenna equipment.
Corrosion-Resistant Construction - Marine-grade materials withstand continuous saltwater exposure, coastal humidity, and harsh marine environments without rust degradation or structural failure common in non-marine mounting hardware.
Professional Marine Installation - Heavy-duty construction provides secure mounting support for marine antennas subjected to wave impacts, high winds, and vessel movement, preventing vibration loosening during offshore operations.
Versatile Deck Mounting - 4-way configuration accommodates various deck layouts, obstructions, and installation requirements on different vessel types from small recreational boats to commercial fishing vessels and marine work craft.

Installation Notes
The OPEK AM903 marine deck mount installs on horizontal deck surfaces, cabin roofs, hardtops, or bimini frames. Determine optimal antenna location considering clearance from rigging, minimizing cable run length, and avoiding interference with vessel operations. Position the AM903 mount and mark mounting hole locations through the 4-way base. Drill appropriate diameter holes through the deck surface, ensuring adequate deck thickness for secure mounting. For fiberglass decks, use marine-grade sealant to prevent water ingress. Install backing plates on the underside of thin deck surfaces to distribute mounting loads. Thread the included stainless steel bolts through the mount and deck, securing with washers and nuts on the underside. Tighten securely without over-torquing fiberglass surfaces. Thread your antenna with standard 1-inch x 14 TPI base onto the AM903 mount. Route coaxial cable through deck glands or existing cable passages. Apply marine-grade sealant around the base perimeter to prevent water penetration. Verify antenna remains secure during vessel movement and re-tighten periodically.
Frequently Asked Questions
What does 1" x 14 thread standard mean?
The 1" x 14 designation refers to standard antenna thread specifications: 1-inch diameter with 14 threads per inch (TPI). This is the universal thread standard for most UHF CB antennas and marine communication systems, ensuring the AM903 accommodates virtually all standard marine and vehicle antennas without adapter requirements.
Is the stainless steel hardware truly marine-grade?
Yes, the AM903 includes marine-grade stainless steel mounting hardware specifically engineered for saltwater environments. Unlike standard zinc-plated or mild steel fasteners that corrode rapidly in marine applications, stainless steel hardware withstands continuous saltwater exposure, coastal humidity, and harsh marine conditions without rust degradation.
Can I install this on a fiberglass boat deck?
Yes, the AM903 is suitable for fiberglass deck installation. Ensure adequate deck thickness for secure mounting (minimum 6-8mm recommended). Use backing plates on the underside for thin deck sections to distribute mounting loads. Apply marine-grade sealant during installation to prevent water ingress through mounting holes.
What is the advantage of 4-way mounting?
The 4-way configuration provides four separate mounting bolt positions around the base perimeter, distributing mounting forces more evenly and providing greater stability compared to 2-way or 3-way mounts. The multiple mounting points also accommodate various deck layouts, obstructions, and installation requirements on different vessel types.
Does this mount work with vehicle antennas?
Yes, any UHF CB antenna with standard 1" x 14 thread will physically fit the AM903. However, this mount is specifically designed for marine deck mounting applications. For vehicle installations, consider vehicle-specific mounts like mirror brackets, bullbar mounts, or magnetic bases more suited to automotive mounting requirements.
