Building on the success of the A430-V, the new A431-V marine VHF antenna includes 20' of low-loss RG-8/X cable permanently attached to the antenna and a high-quality solder-type PL-259 connector for a hassle-free, professional installation. The A431-V uses copper and brass elements for maximum range and efficiency, all enclosed in a stylish UV resistant radome with stainless steel ferrule. Used with standard 1"-14 mounts, this thick-walled fiberglass antenna is well suited for use on hardtops or T-tops on smaller vessels, where the pounding of wave motion can put additional stress on a taller antenna.
