3D Studio

Four interactive models that make antenna behaviour, impedance matching and propagation visible.

These tools are educational simulations. They use simplified physical models, so treat the numbers as illustrations of the principles rather than as predictions for a specific installation. Real installations must follow local regulations and the instructions supplied with the equipment.

Interactive

Antenna Radiation Visualizer

Orbit a live antenna model and watch its three-dimensional radiation pattern change with frequency, length and height.

BS-3D-029→

Interactive

SWR & Tuner Simulator

Adjust a matching network by hand and watch the standing wave on the feedline collapse as the match improves.

BS-3D-030→

Interactive

Propagation Forecaster

Model the ionosphere and see which bands will open between two points over the next twenty-four hours.

BS-3D-031→

Interactive

Morse Code Trainer

Learn Morse with a real audio oscillator, a clickable 3D paddle and a game mode that keeps score.

Loaded on demand

The 3D library is requested only when you open one of these four pages. The home page preview loads it separately and only for that preview. Reference and blog pages never load it at all.

Always degradable

Every tool has a static reference view that shows the same arrangement and the same figures. If WebGL is unavailable, or if you prefer a quieter page, the 2D view is complete on its own.

Built for a desktop

These models need a reasonable screen and a pointer to be useful. On a small screen the static view is shown first, with an explicit button to load the interactive version. Reduced-motion settings stop automatic rotation and animation.
