Frequency beamwidth reader.
Manufacturers publish beamwidth against frequency as a picture. Test planning needs it as numbers. This tool turns one into the other in four guided steps: load the plot, calibrate its axes, trace the curves, and export a clean table.

…or paste a screenshot (Ctrl+V / Cmd+V), or use the file picker on the right.
Beamwidth on the Y axis, frequency on the X axis.
Tip: a loupe follows your cursor over the plot for precise clicks. Points can be undone one at a time at any stage. Everything runs in your browser — the image never leaves your machine.
