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.

The "Best" Random Wire Antenna Lengths Randon wire lengths you should and should not use! 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
27 sie 2024 · 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 ...
When on the trail, at Field Day, or whenever a good antenna is unavailable, a random wire can save the day, but it is important to understand its properties. At multiples of half wavelengths of the transmit frequency the impedance is so high that tuners in most rigs often can't match it.
24 paź 2024 · A random wire antenna length calculator takes the desired frequency range (in MHz) and suggests wire lengths that are less prone to resonance issues. It calculates lengths that are half-wave multiples (like 1/2λ, 1λ, 2λ).
26 kwi 2012 · The shortest antenna that has a chance of tuning all bands has an electrical length of 143 feet and should be trimmed to give a quarter wave resonance at 1.72 MHz.
9 lis 2023 · You can see a table with wire lenghts to avoid and another line in green beginning with "REVISED:" for good random wire lengths. It is also known, that very long random wires do not always give better results. As you can see, a 29' or 35.5' random wire is best.
