About this app

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.

I love this handy app! Makes having to remember formulas a little forgiving, considering I can only remember two or three. Simple and easy to use. And free. Much rather have it and not need it than the alternative.

Apparently from the annoying ads that now pop up I've been using this app over several phones and I've found it very useful for UHF and microwave.
