Sirio 827 (26.4 - 28.4 Mhz) 10M-HAM 3000W Tunable Base Antenna [SIR-CBBA-0827] - One of the best selling 10M-HAM Base antenna in the world, high quality, strong build: Base station antenna, Omnidirectional High power handling capability Low radiation angle for excellent DX Equipped whit excellent multi element ground plane Optional radials ...

Very high quality 5/8 wave antenna with groundplanes. Made from aluminium with Magnesium for better radio conductivity and maximum strength. This is certainly the strongest aluminium antenna available. The large open coil prevents any build up of water or condensation and allows the antenna to handle high levels of RF power.

The Sirio 827 base antenna is one of the most respected antennas around. High performance comes as standard and the 827 will let you transmit much further than most conventional antennas, the build quality is superb, will give many years of service, and ideal also for amateur use on the very popular 10m (28Mhz) band too.

Sirio 827 base antenna, built like a Sherman Tank! Made from high strength large bore Silicon Magnesium alloy tubing to give it maximum strength. The ground plane is composed of 8 aluminum radials which allow a perfect propagation pattern, and the coil is made of high gauge enameled copper wire, to handle high power rating.
