Yagi Calculator will help any radio enthusiast to design and build his/her own DL6WU yagis for VHF/UHF, meeting the criteria developed from the work of Guenter Hoch. I have found this program easy to install. Navigation is also easy and the menu bar features exactly the options needed for the tasks required to develop yagi antennas. These options can be selected from the Task context menu. Selecting the Design Yagi option prompts the program to open a window where you can calculate the length and spacing of elements depending on frequency inputs; size of boom elements; different methods of mounting, etc. Dimensions for existing DL6WU antennas can also be entered.
By simply clicking on the Calculate button in the Design Yagi window you will get printable Yagi results for your design; and the dimensions of balun constructions can be viewed by clicking on the Balun button in the Yagi Results window. If you're not happy with the results, it is possible to return to any window using the Back button. In the Yagi Results window, clicking on the Create YO function will allow you to save your data. The program also allows to calculate SWR for various inputs; gain calculations for long yagi, the stacking distance and gain calculations for 2 yagis, and finally, the Impedance of Parallel Rods and Quarter wave transformers.
- Quick and easy to use.
- No back button in the Impedance window.
