The Sirio BLIZZARD is a powerful CB Base 10m band station antenna that combines the features of the Sirio 827 and a Nylon Ring. It is an omnidirectional antenna that is factory-tuned at mid-band, ensuring excellent performance. With its high power handling capability and low radiation angle, it is ideal for long-distance communication. The antenna is made of durable aluminium alloy and is protected from static discharges with its DC-Ground feature. It also features radial reinforcement and an anti-noise Nylon Ring. 

In terms of electrical data, the Sirio BLIZZARD is a 5/8λ ground plane antenna with a frequency range of 26.4 to 28.4 MHz. It has an impedance of 50Ω and offers 360° omnidirectional radiation with linear vertical polarization. The antenna has a gain of 1.5 dBd and 3.65 dBi, and a bandwidth of at least 2000 KHz. It has a SWR of ≤ 1.1 at the resonant frequency and can handle a maximum power of 1000 Watts (CW) continuously or 3000 Watts (CW) for short periods. The feed system/position is a transformer DC-ground/base, and it has a UHF-female (SO-239) connector. 

In terms of mechanical data, the Sirio BLIZZARD is made of aluminium, steel, copper, and nylon. It has a wind load/resistance of 264 N at 150 Km/h or 130 Km/h and a wind surface area of 0.23 m². The antenna has a height of approximately 6700 mm (21.98 ft) and weighs around 6000 grams (13.23 lb). The radial length is approximately 1400 mm, and it can be mounted on a mast with a diameter of 35-39 mm. The packaging includes one antenna, one Nylon Ring, and a User Manual in English.
