Portable No Tune End Fed Half Wave Antenna EFHW Antenna Assembled For Radio Communications DIY
Description:
It is a single-band 80m-10m end-fed half-wave linear antenna. It is designed as a highly portable wired antenna that can be easily set up as an inverted V, horizontal, inclined or vertical radiator (in the case of higher frequencies). Your feeder line is essentially balanced, so there is no need for a separate feeder line. The high-impedance half-wave line is matched with your 50-ohm feed point through an integrated impedance matching toroidal transformer, and the rated power is 10W.
Use a high-voltage capacitor on the transformer primary with a specific radiator length to further expand and reduce SWR within the range of 80m-10m.
It is designed to be used without a tuner, and after optimizing the driven element, the SWR of any part of the frequency band is ≤ 1.2.
Specifications:
- Impedance: 50 ohms
- Size: 100*71mm
Package Included:
- 1 x Antenna
Note: It is assembled and ready for use.
