27 MHz 1/4 wave vertical antenna delivered with 3 wire radians. Very robust tubes with large diameters and thicknesses (2 mm), wide bandwidth, very low SWR. Connection to the 50 ohm coaxial cable directly by SO-239 (no balun or other adaptation system). On perfect ground the gain reaches 5.15 dBi and the radiation lobes favor DX.
