This antenna wavelength calculator can be used to determine the physical length of an antenna’s electromagnetic wave in free space. This can be useful for determining antenna ground plane requirements, antenna spacing requirements to prevent coupling in for multi-antenna systems, or other situations where the antenna’s wavelength is needed.
This calculator can be used to design a Quarter Wave Ground Plane antenna, with radials. The radiating element is a quarter wave (λ/4) and the radials are 12% longer. There are usually four radials, three being a minimum, but you could use up to six.
14 sty 2007 · From what I understand a 1/2 wave antenna will perform better than a 1/4 wave, and a 5/8 wave will perform better than a 1/2 wave. So is it safe to assume a full wave will perform best of all, or is that not always the case?
This calculator gives the lengths of the radiating element of a quarter wave (λ/4) ground plane monopole and the radials. Calculator. Enter. Frequency or wavelength of operation, Velocity factor % increase of radial length over the main vertical radiating element (0% means the radial length is the same as the monopole)
1/2 wave Dipole Calculator. The dipole antenna is probably the easiest to make. All you need is 2 pieces of wire 3 insulators and a suitable feed line. To make it even easier you can calculate the lengths of wire required to construct a 1/2 wave dipole using this page. Frank VK3BFC
16 paź 2024 · How many radials should be used? This calculator gives the lengths of the radiating element of a quarter wave (λ/4) ground plane monopole and the radials. Enter. and the tool will provide the lengths of: A quarter wave (λ/4) antenna designed for 20 meter applications (15 MHz) has a length of 3.3 meters.
Use this online calculator to determine the length of a quarter-wave antenna from the frequency. Both metric and English units of measurement are supported.
