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.

Antenna length based on the following formulars: 1/2 λ dipole (feet)= 468 / frequency in Mhz. 1/2 λ dipole (meters) = 142.65 / frequency in Mhz: Full wave loop (feet) = 1005 / frequency in Mhz: Full wave loop (meters) = 306.32 / frequency in Mhz: Cut wire slightly longer for connecting insulators and pruning.
This calculator is an aid for determining antenna element lengths, based on Frequency, Type (Wire or Tubing), and Diameter (AWG#, inches, mm) of the element. At the top of the calculator, enter the Frequency (1 to 30 MHz) of interest.
Ham Radio HF/VHF Antenna Lengths Chart. Here is a handy chart for determing 1/4 wave verticals, 1/2 wave dipoles, and full wave loop lengths. All antenna lengths in the information below are in feet and are the results based on the standard formula of 468 / FMhz = total length in feet.
Cushcraft R7 Vertical AD4IE end-fed as inverted L. 1⁄2 wave antennas can be fed from the end (voltage feed) • Inverted L is popular on 160 and 80 meters where vertical height is often lacking. Many are 1⁄4 wavelength, but some longer, which allows easy multiband operation.
The Single Wire End Fed Antenna is probably the simplest antenna to use. But when you start looking around, you find that no one can agree on what length to use. Some say any length will work, some stress odd multiples of 1/4 wavelength, while others lean toward even multiples of 1/2 wavelengths.
29 kwi 2020 · The quality of your VHF radio signal is determined by the length of the antenna you choose, the position in which you install it and how you adjust it to pick up a signal. Finding the perfect VHF antenna length is easy if you know what to look for.
