Yagi Designer 2.0 is a Yagi antenna calculator that can easily display E-Plane, horizontal radiation pattern, and H-Plane the vertical radiation patters, as well as to display antenna characteristics, in Gain, F/B ratio and feed point resistance and reactance. Yagi antenna calculator, yagi antenna dimensions, learn to build a yagi antenna, guide to yagi antennas. Simple 3 element Yagi Beam Calculator for Amateur Radio.
Yagi Calculator - Yagi Calculator is a free Windows program that also runs well on Linux, Ubuntu 8.10 under Wine, to produce dimensions for a DL6WU style long Yagi antenna. Long yagis are commonly used from the 144MHz amateur band to the 2.4GHz band.
An application designed to generate data for the construction of long Yagi antennas for vhf and UHF use.
Yagi Calculator is a program build to produces dimensions for a DL6WU style long Yagi antenna.
Long Yagi are commonly used from the 144MHz amateur band to the 2.4GHz band.
The DL6WU Yagi is highly regarded as being easy to build with repeatable results, broad bandwidth and a useful pattern.
Here are some key features of “Yagi calculator”:
- Calculation of the element length and element spacings of a yagi for a particular frequency
- Different size materials for boom and elements are catered for as are different methods of mounting
- Dimensions of baluns are calculated
- Provision for entering the dimensions of an existing DL6WU antenna for optimization through an external program or to gather information on its gain, beamwidth etc.

This page covers 3 element Yagi Antenna calculator. The formula and basics of Yagi Antenna Calculator are also explained with example.The calculators for other antenna types such as parabolic,horn,dipole and patch are also mentioned.
What is Yagi Antenna ?
The simple Yagi Antenna is shown in the figure-1. It consists of three elements viz. director, dipole andreflector. It may have one or multiple directors.
Dipole (i.e. Driven Element): It is the feed point where feedline is usually attached from transmitter.This helps in transfer of energy from transmitter module to antenna.The feed point is located at the center of the driven element. It becomes resonant when its electrical lengthis about half of wavelength of frequency.
Director: It is designed mainly for receiving EM waves. It is shortest of parasitic elements.It has length which is 5% short compare to driven element. It has resonant higher compare to driven element.It helps to achieve desired gain and directional pattern.The spacing between directors usually range from 0.1λ to 0.5λ or more.The Gain of Yagi Antenna depends on length of antenna array and do not depend on number of directors usedin the design.
Reflector: It is placed at rear of dipole or driven element.The length is usually 5% more compare to driven element. The spacing of reflector from driven elementis about 0.1 λ to 0.25 λ. The spacing also depend on bandwidth, gain, F/B ratio and sidelobe patternspecifications.
The following are the basic specifications considered in selecting Yagi Antenna and performing calculationsin this yagi antenna calculator.
• Bandwidth
• Impedance
• Gain
• Front to Back Ratio
