The single-band 80m-10m end-feed halfwave linear antenna provides the antenna. It is designed as a highly portable wired antenna that can be easily set to an inverted V-shaped, horizontal, tilted or vertical radiator (under high frequency situations). The SWR is further extended and reduced in the 80m-10m ranges using a high voltage capacitor on the primary of the transformer with a specific radiator length. It is designed to be used without the use of a tuner, and has a SWR 1.2 for any part of the frequency band after optimizing the slave component. Features: Possess smooth surface and simple installation, with higher passing performance of large and small currents, larger area heat dissipation, and longer running time. The single-band 80m-10m end-feed halfwaves linear antenna provides the antenna. It is designed as a highly portable wired antenna that can be easily set to an inverted V-shaped, horizontal, tilted or vertical radiator (under high frequency situations). Your feed antenna is essentially balanced, so no separate feeder is required, with stable structure and high operation performance. The high impedance halfwaves line is matched to your 50 ohm feed point via an integrated impedance matching toroidal transformer rated at 10 watts. The SWR is further extended and reduced in the 80m-10m ranges using a high voltage capacitor on the primary of the transformer with a specific radiator length. It is designed to be used without the use of a tuner, and has a SWR 1.2 for any part of the frequency band after optimizing the slave component.
