3 Band antenna for 20, 15 and 10m band uses a common feed line. Input power limited by feed line only. Low SWR, excelent F/B, excelent F/S ratio. Wind survival speed 130 km/h. A very flexible alloy EN AW 2024 (not EN AW 6060) is used for the elements. All fasteners (screws, screw nuts, ets are from stainless steel).
Easy to connect coaxial cable with PL-259 connector.
