Cantennator calculates the dimensions of popular DIY antennas for Wi-Fi 3G-5G and other digital networks including On Air TV as well as HAM radio antennas with export to computer NEC-based modeling programs. It calculates the dimensions of Yagi-Uda BiQuad Double BiQuad antennas Helical Disk-Yagi Collinear Moxon-rectangle and many other antenna types. For calculations you only need to know the device's operating mode (4G 5G or Wi-Fi) or operating frequency. You could print and share result of the calculation. In addition the application allows you to evaluate the energy balance and line of sight of the radio communication line as well as the attenuation in the coaxial cable.
