Rupp Standard Antenna Mount Support w/4-Way Base & 1.5" Collar

The Rupp Standard Antenna Mount Support with 4-Way Base and 1.5" Collar is a marine-grade mounting system engineered for secure antenna installation on vessel cabin sides and exterior structures. Built from forged and anodized aluminum, this antenna mount combines structural integrity with corrosion resistance—essential for offshore and saltwater environments where standard steel mounts fail within months.

The oval 4-way base distributes load across multiple mounting planes, critical for managing vibration and lateral stress from high-frequency transmission. The 1.5-inch locking collar accommodates standard antenna shafts while allowing quick lowering for passage under bridges or tight moorings—a field-tested convenience feature that eliminates the need to disassemble the entire mount. Anodized aluminum finish resists oxidation and maintains appearance through repeated saltwater exposure, outperforming painted alternatives that chip and corrode. The design ships without spacers or bolts, allowing integration with existing cabin hardware and custom mounting configurations.

This mount is specified for patrol vessels, commercial fishing platforms, and recreational cruisers where VHF, SSB, and cellular antennas require stable, weather-resistant support. Operators managing multi-antenna arrays value the 4-way base for its ability to position antennas at optimal angles without lateral sway. Weight at 1.05 lbs keeps structural loading minimal, important on fiberglass vessels where bracket mass compounds stress on cabin walls over time.

Rupp Marine antenna systems are industry-standard in commercial and military maritime applications. This support represents the baseline configuration for operators requiring dependable RF performance without integrated cable routing or elaborate mast systems—pure functionality in aluminum form.
