WWW.AERIAL-51.COM is a new antenna concept for combining extremely lightweight wire antennas with lightweight telescoping fiberglass poles, enabling rapid deployment of efficient antennas (within minutes) at heights previously unobtainable with a portable product.

Model 404-UL is an ultra lightweight, asymmetrical dipole for operation on 7 or 8 shortwave bands. It is constructed using very light, yet strong components. All hardware is stainless steel. The antenna radiator is made from CQ-534 insulated multi‐strand copper‐clad steel wire with 1mm outer diameter, which has very low wind load and weighs only 31gramm (!!) yet it still maintains a breaking strength of 10kg. The antenna comes including 12m coax which despite the low weight (only 185g) shows only very modest losses (~1dB on 40m, < 2dB on 10m). The ultra lightweight matching unit not only matches the coax to the antenna, it also provides excellent choking resistance to suppress common mode current.

Its super lightweight makes Model 404-UL ideal for portable use with any of the Spiderbeam telescoping fiberglass poles (12/18/22/26m), turning your little pistol station into a BIG GUN.

No other portable antenna on the market combines so many bands with such high efficiency and such low weight!
