2 Band antenna for 40 and 20m band ( 3 ele. 40 m + 5 ele. 20 m ) uses a two feed lines. Input power limited by feed line only. Low SWR, excelent F/B, excelent F/S ratio. Wind survival speed 170 km/h. 3 elements 40 m, without coils, which provides a wideband antenna with SWR below 1: 1.4 in the whole band. A very flexible alloy EN AW 2024 (not EN AW 6060) is used for the elements. All fasteners ( screws , screw nuts, etc are from stainless steel.
Easy to connect coaxial cable with PL-259 connector.
