Random Wire Antenna Lengths. A so-called random wire antenna is an end fed antenna. As typically installed, it is a compromise antenna but great for portable use because it is easy to pack and easy to install.
Learn how to avoid the most common pitfalls of random wire antennas by choosing the right lengths for different HF bands. See a table of lengths to avoid and a list of good lengths based on multiples of half wavelengths.
27 sie 2024 · All you need for a random wire antenna is some wire, your tuner, one or more supports up as high as you can get them to string the wire from the supports to the tuner, at least one or two insulators and a little time.
26 kwi 2012 · Learn how to calculate the optimal length of a random wire antenna for amateur radio bands using a program and a table. Find out the gaps in the quarter-wavelength frequency spectrum and the preferred electrical lengths of the antenna.
A random wire antenna is a simple and versatile type of antenna that can be used for radio communication across a wide frequency range. Learn what it is, how it works, and why it may not be suitable for some applications.
Learn how to use a 35' random wire antenna with a 9:1 UnUn transformer to operate on multiple bands with a tuner. See the ideal lengths, configurations, and SWR readings for this antenna system.
