MARINE ANTENNA 3DB GAIN SLIM JIM 136-174 Mhz

Slim Jim Architecture: The antenna uses a folded dipole design derived from the classic “Slim Jim” geometry — offering improved performance over simpler whip antennas by shaping the radiating elements for better current distribution and a low-angle radiation pattern.

Durable Materials: Typically built with fiberglass radome and corrosion-resistant metallic elements, the antenna is designed to withstand harsh marine environments including UV, saltwater spray, and strong winds.
Weatherproof Build: All external components are sealed for ingress resistance, offering protection against moisture and salt corrosion for long-term reliability.
