windows default iconYagi calculator Publisher's description

An application designed to generate data for the construction of long yagi antennas for vhf and uhf use.

Yagi Calculator is a 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. The DL6WU yagi is highly regarded as being easy to build with repeatable results, broad bandwidth and a useful pattern.

The program on this site was developed in the early 90s as a DOS program. Time moved on and so did operating systems, so the 2003 version was an opportunity to convert to a Windows environment and update the information and modify some of the algorithms.

Features of the free but copyrighted program include:
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, there is provision for entering the dimensions of an existing DL6WU antenna for optimisation through an external program or to gather information on its gain, beamwidth etc. A handy SWR calculator and feedline loss calculator are included as part of the package. Stacking information is also provided as are estimates of gain. A helpfile is included that covers many aspects of yagi design as well as helping with the operation of the program.
