Sirio GPE 27 5/8λ Base 10m Ham Antenna 250W Continuous, 1.2dBd Gain, Tunable 26.4-29MHz, Ground Plane

The Sirio GPE 27 5/8 is a high-performance, 5/8λ ground plane base station antenna engineered in Italy specifically for 10-metre amateur radio use. With 250W continuous power handling (750W short time CW), a wide tunable frequency range of 26.4–29 MHz, and a gain of 1.2 dBd (3.35 dBi), it delivers excellent omnidirectional performance across the full 10m band. Standing at 5950mm (19.52ft) tall and designed for on-mast mounting, it's constructed from aluminium, copper, galvanised steel, and nylon for robust, long-lasting outdoor performance.
