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%.There are usually four radials, three being a minimum, but you could use up to six.

 

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.Embed Share via.

 

Calculate the required dimensions for a quarter wave antenna construction for any given frequency. Enter the required frequency in MHz and the antenna designer.Various antennas from a quarter-wave to a full-wave vertical can be calculated below.

 

This calculator will help you to calculate the different wavelength of antennas based on the Where, Full Wave = Half Wave = Quarter Wave = Quarter-Wave Vertical Antenna Length Calculator A quarter-wavelength antenna is easy and inexpensive to build and can be an effective antenna with a low angle of radiation that is, power is radiated out, not up.

 

This calculator is designed to give the vertical length (height) of a quarter wave ground plane antenna, and the length of each of the four radials.Reviewed by Bogna Szyk and Jack Bowater.

 

This calculator assumes propagation in a free space, earth atmosphere environment. Full wave, half wave, and quarter wave antenna structures can be selected.We'll assume you're ok with this, but you can opt-out if you wish.

 

Use our simple calculator to determine approximate dimensions of materials needed to build a vertical antenna. Choose from quarter-wave, half-wave.Calculate various antenna dimensions, determine best height above the ground, look up coaxial cable properties, check the ideal stripping dimensions for mounting various connectors, and more.
