SEAVIEW M1 or M2 Mount Spreader Kit | Dual GPS Antenna mounting with Concealed Cable Routing | Configure for Radar or satdome with Included Extension Posts | AFT-Angled Design eliminates Interference

Seaview Modular Spreader Kits are engineered to expand your mast mount's capabilities by providing dedicated mounting positions for GPS antennas and other accessories, with a three-piece bolted construction featuring a center midsection and two tapered spreaders that angle aft to prevent interference with your primary radar or satdome installation. Designed with internal cable routing channels, these spreader kits allow you to run all wiring from your GPS units or antennas completely concealed through the spreaders and directly into your mast mount, delivering both enhanced security and a remarkably clean, professional appearance that eliminates exposed cables. The intelligent dual-configuration design adapts to your specific installation: use the included stainless steel extension posts to raise GPS antennas above closed dome radars for optimal signal reception, or mount GPS units directly to the spreaders when paired with satdomes since GPS signals travel horizontally while satellite communications travel vertically to orbiting satellites. Constructed from marine-grade powdwer coated aluminum and assembled with four heavy-duty bolts per spreader arm, each joint is sealed with rubber gaskets to prevent water intrusion and ensure long-term reliability in harsh marine environments. Every Spreader Kit includes the center midsection, two tapered spreaders, all mounting hardware, rubber gasket seals, and two stainless steel 1"-14 threaded adapters (SP7SSV2) for universal GPS antenna compatibility, providing everything you need for a complete installation that maximizes your mast mount's functionality while maintaining the sleek aesthetic Seaview is known for.

• Internal Cable Management System | Route all GPS and antenna wiring completely concealed through the hollow spreader arms and directly into your mast mount. This integrated cable routing protects your connections from the elements while delivering an exceptionally clean installation that eliminates unsightly exposed cables.
• Dual-Configuration Design | Adapts perfectly to either closed dome radar or satdome installations. Included stainless steel extension posts raise GPS antennas above radar domes to prevent horizontal signal interference, while satdome configurations mount GPS units directly to spreaders since satellite signals travel vertically and won't conflict.
• Interference-Free Tapered Design | Spreaders are precision-engineered with an aft-angled taper that positions accessories away from your primary radar or satdome, ensuring unobstructed signal transmission and optimal performance for all your marine electronics.
• Durable Construction | Four heavy-duty bolts secure each spreader to the midsection with rubber gaskets positioned between every joint, creating a watertight seal that prevents moisture intrusion and ensures lasting durability in the harshest marine conditions.
• Complete Installation Package | Each kit includes the center midsection, two tapered spreaders, all stainless steel mounting hardware, rubber gasket seals, and two stainless steel 1"-14 threaded adapters (SP7SSV2) for immediate GPS antenna mounting compatibility. Available in two sizes: SP1MODV2 for mounts ending in "M1" and SP2MODV2 for mounts ending in "M2".
