   19 sty 2017 · I want to use an end-fed wire antenna, but what would be the best length of wire for the 20m and 40m bands? Is there a way to work this out? This is assuming a tuner will be used.

   Magic Numbers: These are antenna lengths that users of End-Fed Antennas have said, worked well for them. I collected them from various web sites. It is said that, these lengths should give you a 2.2:1 SWR on all bands.

   We can divide end-fed antennas into 4 general groups, based on the required impedance matching: quarter wave antennas (or similar) that often don’t need additional matching; short antennas, less than a quarter wave; half-wave antennas, or multiples thereof. other, including multiband operation

   The random wire antenna is probably one of the least expensive, easiest and cheapest HF antennas to use if you have a tuner and you want to get the "most" out of a length of "random" wire without having to pull out that calculator, doing the math, getting the center insulator built or bought, running the feedline, and all the rest that goes ...

   23 lut 2023 · I explain the basics of the End Fed Half Wave (EFHW) Antenna, and how i calculate the lengths of my antenna for my targeted bands. I also go over some harmonics and how this can be used to combine a couple of bands on a single antenna.

   Par sells a multi-band end fed non-resonant wire antenna that's 40ft long. I know two people that use this antenna and like it. The wire is non-resonant over a wide range of lengths but resonant at a specific length. There's no exact optimal length for a non-resonant wire antenna for every location. This is a good reference. https://palomar ...

   27 paź 2022 · A basic rule of thumb for "random wire" antennas is: At least a quarter-wave long on the lowest band you want to use, and not a half-wave on any band you want to use. If you search for "best random wire antenna lengths" there are some good sites that explain everything and give tables of wire lengths for different band combinations. Have fun!
