The Antenna Design Dashboard is a quick “starting-point” calculator for common beginner-friendly antennas. Enter your target frequency, choose the antenna type (dipole, vertical with radials, EFHW or random wire), and the tool will generate recommended cut lengths in your chosen units. A simple diagram updates with your measurements, and can be enlarged for easier viewing on mobile or at the workbench.

Below the design panel you’ll also find a set of built-in converters for frequency, length, area/volume, temperature and common electrical units (including dBm ↔ watts). Results are intended as practical starting values—final trimming and tuning is always recommended, as installation height, wire thickness/insulation and local surroundings can affect resonance.
