Seaview 30" Tapered Closed Dome Aft Leaning Radar Mount w/Removable Spreaders 10x10 Base Plate

Seaview 30" Tapered Closed Dome Aft Leaning Radar Mount w/Removable Spreaders 10x10 Base Plate

The Seaview 30" Tapered Closed Dome Aft Leaning Radar Mount is engineered to support most 18" to 24" closed dome radars as well as open array radars up to 4.5 feet in length. Designed with a 10x10 base plate and an aft-leaning tapered profile, this mast combines a sleek marine appearance with functional versatility for a wide range of radar installations.

Seaview takes durability seriously. Each tapered mast begins in raw aluminum form and is processed through Chem Film — a chemical conversion coating that provides a protective layer over the aluminum substrate. Following the Chem Film treatment, the mast undergoes a 3-part epoxy primer application before receiving a final powder coat finish. This multi-stage finishing process ensures superior corrosion resistance and a long-lasting appearance that stands up to the harsh marine environment.

Installation is straightforward and hassle-free. The lower mounting plate is designed to accept most standard 18" and 24" radar domes as well as open array radars up to 4.5 feet, eliminating the need to drill mounting holes and enabling a quick, clean setup.

The removable spreaders are fitted with standard 1-14 threaded nylon fittings, chosen specifically to eliminate corrosion at connection points. Note that antennas mounted on the spreaders should not exceed 4 feet in length. The spreaders are also designed to be removable to reduce shipping dimensions and associated costs.

A top mounting plate is included and can accommodate an optional light fixture, adding further utility to the mast. The oval hollow mast section provides a dedicated internal channel for clean and organized cable management.
