"Designed for mast mounting on sailboats or for smaller craft that ""heel"" on the waves. Sends out a broader signal than a 6dB antenna, ensuring better signal dispersal in rough seas (but less range). Shakespeare Flexible whip styles provide the best horizon-to-horizon coverage. Stainless steel finish with tin-plated copper elements. 3', 1-piece antenna with chromed brass ferrule. 15' RG-58 lead-in and PL-259 connector. Manufacturer's 2 year warranty. Mount not included, please order separately."
