Scanstrut SC20-BLK Mast Mount

The Scanstrut SC20-BLK Mast Mount is the industry-standard solution for anglers and boaters who need reliable antenna placement without consuming valuable deck space. Designed by Scanstrut—a brand trusted worldwide for marine electronics integration—this mast mount delivers a cost-effective alternative to permanent installations, allowing you to mount radar domes, satcom systems, and navigation antennas with confidence. Whether you're running a center console, cabin cruiser, or sportfishing boat, this mount solves the spatial constraints that plague modern vessel layouts.

The SC20-BLK employs a precision-engineered bracket design that distributes antenna weight evenly across your mast structure, minimizing vibration and signal degradation during heavy seas or extended trolling sessions. Its compact footprint—measuring just 6 by 4 inches at the mounting surface—fits tight spaces without interfering with boom rigging, spreader cables, or radar sweep radius. At 3.1 pounds, the mount itself adds minimal weight aloft, a critical factor for maintaining boat balance and fuel efficiency. The black powder-coat finish resists saltwater corrosion and UV fading, ensuring years of reliable service in harsh marine environments.

This mast mount suits both professional charter captains and recreational offshore anglers who demand repeatable positioning and easy antenna servicing. Installation requires basic fastening to your existing mast—no welding or permanent modifications—making it ideal for rental fleets and boats with multiple sensor packages. The SC20-BLK accommodates standard marine antenna connectors and works seamlessly with Radome systems and compact satcom units, providing a universal solution for radar, GPS, and communications upgrades without structural compromise.
