The single band 80m-10m end-fed half-wave wire antenna provides the antenna, which is designed as a highly portable wire antenna that can be set up as an inverted V, horizontal, inclined or vertical radiator (in the case of higher frequencies). Your feed line is essentially a balanced ground, so there is no need for a separate feed line The high-impedance half-wave line is matched to your 50 ohm feed point via an integrated impedance-matching toroidal transformer, rated at 10 watts. Further enlargement and reduction of SWR in the range of 80m-10m using high voltage capacitors on the transformer primary with specific radiator lengths. It is designed to be used without a tuner and has a SWR 1.2 for any part of the band after optimizing the components.
