FOR HORIZONTAL ANTENNAS, HEIGHT = MIGHT!!<\/strong><\/p>\n\n\n\n

AERIAL-51<\/strong> 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.<\/p>\n\n\n\n

Model 404-UL<\/strong> 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 UL-wire \/ Liv-2Yz (ultra light armid synthetic fibre and copper strands, Insulated). 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.<\/p>\n\n\n\n

Its super lightweight makes Model 404-UL<\/strong> 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<\/p>\n\n\n\n
