Seaview 4 Degree Wedge Mount For Most Open Arrays

The Seaview 4 Degree Wedge Mount for Most Open Arrays is an essential installation component for mariners running open array radar systems on modern fishing and cruising vessels. After years on the water, any experienced boater knows that radar mounting height and angle directly affect signal quality and target acquisition—especially in variable sea states where even a few degrees of tilt can mean the difference between clear returns and wasted scanning patterns. This wedge mount solves a critical compatibility gap, allowing you to fine-tune your antenna's vertical plane and optimize performance across multiple radar platforms without expensive custom fabrication or unnecessary downtime.

Engineered with a precisely machined 4-degree wedge geometry, this mount accepts open array antennas from industry-leading manufacturers including Furuno, Garmin, Simrad (excluding Halo models), Koden, and Northstar—covering the vast majority of professional and recreational radar installations. The rigid aluminum construction weighs only 4 pounds, minimizing added topside weight while maintaining the structural integrity needed for saltwater and freshwater service. The direct-mount design eliminates adapter chains and loose tolerance hardware, reducing vibration transmission to your mast or hardtop and improving signal stability during heavy weather or aggressive maneuvering.

Installation is straightforward for boatyard technicians or experienced DIY installers familiar with marine electronics. The 4-degree wedge angle accommodates most pilothouse and tower mounting scenarios where standard vertical alignment either reduces antenna efficiency or creates blind spots in shallow-water operation. Verify compatibility with your specific radar model and mounting surface before ordering; the mount accepts standard open array brackets from the listed manufacturers and requires basic marine-grade fasteners for secure attachment. For anglers running Furuno or Simrad systems, this wedge delivers measurable improvement in near-field target definition and clutter rejection—critical advantages when reading structure-rich inshore grounds.
