![]() Version 2.6.17 on 15 July 2015 fixed a bug when restoring a saved file. Latest Version is 2.6.19 and reworks the resizing and placement of windows. ![]() 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. The program on this site was developed in the early 90s as a DOS program. The DL6WU yagi is highly regarded as being easy to build with repeatable results, broad bandwidth and a useful pattern. Long yagis are commonly used from the 144MHz amateur band to the 2.4GHz band. 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. Note: where countries use a comma for decimals you may need to change your country code otherwise MMANA files will not run. A helpfile is included that covers many aspects of yagi design as well as helping with the operation of the program. Stacking information is also provided as are estimates of gain. A handy SWR calculator and feedline loss calculator are included as part of the package. ![]() maa files for MMANA-GAL optimiser.įeatures 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. ![]() If you run Vista I recommend you run it as Administrator. No changes were made to the essential algorithms apart from the additions needed to cater for alternate boom and element material shapes. There have been minor fixes to improve reliability in different machines and better program flow. ![]()
