Let's Build an EFHW Antenna. If you attended Field Day 2022, you may have been one of the students that learned how to build an end fed half wave Antenna and actually got to build one and take it home. For those that were not able to do so, this page is for you. Building antennas is a fun learning experience for any ham operator and one that ...
I came across the following antenna which covers the 80-10m bands with no traps and just one loading coil. It is called the EFHW-8010 . It is simply a half wave end-fed on 80m which will resonate on all multiples of that frequency, loaded with a small inductance near the feed end.
Here are instructions for making a multiband end-fed half-wavelength antenna that works on 17, 20, 30, and 40-meter bands. Materials (pictured) A/B. Solid Core Wire (two colors, 24-gauge recommended)
Antena End Fed – wielopasmowa antena, która dla wybranych pasm będzie pracować bez konieczności stosowania skrzynki antenowej. Świetna antena do pracy w terenie, podczas aktywacji gmin PGA, parków jak również szczytów górskich w programie SOTA. Lekka antena drutowa zasilana z jednego końca.
The Zeppelin antenna consists of a half wavelength of wire fed by a quarter wave length of transmission line. The half-wavelength of wire has a high feed resistance, and would require a high voltage to drive
27 sty 2017 · A shortened multi-band End-Fed Half Wave (EFHW) antenna for 80-10m. This is a shortened multiband antenna, about 23m long, for 80m-10m that offers low SWR (1.3:1) on 80m and 40m, and below 3:1 on 20, 15 and 10m. The antenna has almost 300kHz bandwidth on 80m between 3:1 SWR points.
4 sie 2020 · This is the page on the End-Fed Half-Wave antenna with a 49:1 transformer. This is a multiband antenna without the need for any tuner (which is the best type of antenna).
