Seaview Mast Platform for 18" Satellite Dome Antenna (SVW-SM-18-A)
Mount your 18" satellite dome at the masthead with confidence using the Seaview SM-18-A Mast Platform (SVW-SM-18-A) — a purpose-built, heavy-duty mounting platform engineered to securely attach an 18" satellite dome antenna to a vessel’s mast.
