Sirio Cruiser Marine VHF Antenna 100W, 154-162.5MHz, No Ground Plane, 5.5m White Cable

The Sirio Cruiser is a premium, 1/2-wave base-loaded marine VHF antenna engineered for professional and leisure marine communications. Designed to work without a ground plane, it's ideal for GRP (fibreglass) and wooden hulls where a ground plane is not available. Covering 154–162.5 MHz at SWR ≤2:1 with a bandwidth of 8.6 MHz, it delivers 100W power handling and a gain of 0 dBd (2.15 dBi) with a 360° omnidirectional radiation pattern. The transformer DC-ground feed system provides inherent lightning protection. Supplied with a 5.5m white RG-58 C/U coaxial cable directly connected, and featuring a 180° adjustable whip for flexible positioning. The high-quality white fibreglass conic whip with stainless steel hardware blends seamlessly with any vessel.
