3.5 ft open array antenna

The Furuno XN10A is a 3.5 ft open array antenna built for marine navigation. It serves vessels that need reliable target detection on open water. The unit is supplied new and ready for installation on compatible radar systems.

48 nautical mile range with 2.2° beam

The antenna provides a maximum range of 48 nautical miles and a horizontal beam width of 2.2°. This combination delivers clear separation of targets at distance. Performance naturally diminishes beyond the stated range or in heavy precipitation.

Open array construction for mast mounting

The open array design reduces wind loading compared to enclosed domes, making it suitable for mast or radar arch mounting. Its 3.5 ft aperture balances resolution with a manageable profile for a variety of vessel sizes. The California Proposition 65 warning applies to this product.

Questions about this item

Will the 3.5 ft open array antenna work with my existing Furuno radar display unit?

The XN10A/3.5 is a 3.5 ft open array antenna designed for compatible Furuno radar systems; it offers a 2.2 degree horizontal beam width and a 48 nautical mile range.

How can I verify the 2.2 degree beam width is performing correctly after installation?

After setup, observe the radar picture for sharp target separation at distance; the 2.2 degree horizontal beam width should resolve closely spaced contacts clearly out to the 48 nautical mile range.
