Spiderbeam Aerial 51 LAMCO Barnsley
404-UL Ultra Lite Weight HF Antenna
Aerial 51 404-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.
