Rupp Four-Way Oval Antenna Base Assembly

The Rupp Four-Way Oval Antenna Base Assembly is a marine-grade mounting solution designed for serious anglers and boaters who demand reliable communication and navigation equipment. This four-way base provides multiple mounting points for antennas, allowing you to run VHF radio, GPS, and other essential electronics simultaneously without cluttering your hardtop, tower, or cabin roof. Built by Rupp Marine, a trusted name in sport-fishing hardware, this assembly handles the harsh saltwater and freshwater environments where anglers spend their days.

Engineered with black anodized clevis hardware and forged aluminum fittings, the Rupp Four-Way Oval Antenna Base Assembly resists corrosion and maintains structural integrity under constant UV exposure and moisture stress. The oval footprint distributes load evenly across mounting surfaces, reducing stress concentration that can lead to cracking or loosening over time. Forged aluminum construction provides superior strength-to-weight ratio compared to cast alternatives, ensuring your antenna array stays secure through rough seas and constant vibration. The included clevis (part 09-1088-23) accepts standard antenna studs and allows for angular adjustment to optimize signal reception.

Whether you're running a center console, express cruiser, or traditional sportfisher, the Rupp Four-Way Oval Antenna Base Assembly fits seamlessly into existing hardtop or tower infrastructure. Anglers and offshore operators benefit most from four-way configurations, as they eliminate the need for multiple single-antenna bases that create weak points in the mounting structure. Professional installers and DIY boaters alike appreciate the forged aluminum construction, which doesn't require constant re-tightening like lesser assemblies. For tournament fishermen and commercial operators, reliable antenna mounting directly impacts communication safety and fish-finder performance—making this Rupp Marine assembly a proven investment in vessel capability and crew safety.
