Chameleon Antenna Stainless Steel Marine Adapters are precision-engineered adapters that bridge the gap between marine and amateur radio antenna systems. Crafted from marine-grade stainless steel, they offer exceptional strength and corrosion resistance for long-lasting performance in harsh environments. MARINE-A adapters seamlessly adapt 1.0-14-inch marine threads (both male and female) to the standard 3/8-24-inch threaded stud that’s commonly used in amateur radio applications, and vice versa.

Key Benefits:

Seamless Compatibility – Converts 1.0-14-inch marine threads (male or female) to the standard 3/8-24-inch threaded stud commonly used in Amateur Radio applications.

Versatile Applications – Ideal for mounting marine HF antennas to ham radio setups or deploying Chameleon vertical antennas on boats and marine mounts.

Built for Reliability – Rugged 100% stainless steel construction ensures durability and secure connections in any condition. Made in the USA
