Portable No Tune End Fed Half Wave Antenna Assembly

• The single-band 80m-10m end-feed half-wave linear antenna provides the antenna. It is designed as a highly portable wired antenna that can be easily set as an inverted V-shaped, horizontal, tilted, or vertical radiator (at higher frequencies)..
• Your feeder is inherently balanced, so no separate feeder is required. The high-impedance half-wave line is matched to your 50-ohm feed point through an integrated impedance-matching toroidal transformer with a rated power of 10 watts..
• Use a high-voltage capacitor on the primary of the transformer with a specific radiator length to further expand and reduce the SWR within the range of 80m-10m..
• It is designed to be used without the use of a tuner, and after optimizing the driven element, SWR ≤ 1.2 for any part of the frequency band..
• Package Included: 1 x Portable No Tune End Fed Half Wave Antenna.
