Rybakov NEC Radiation Pattern Laboratory

Use the Current Governed Pattern Library

The former static Rybakov plot gallery has been retired. Static exports can become separated from their exact configuration, revision, assumptions, and customer explanation.

The current Pattern Library keeps every accepted model with its customer coverage map, conventional paired engineering plot, interactive 3D view, configuration boundary, and field interpretation.

Open the current Rybakov patterns

What the Pattern Library Can Show

  • How radiator and return-current geometry affect the radiation pattern.
  • How principal elevation and azimuth coverage change with the selected configuration and band.
  • Which modeled assumptions and limitations apply before translating a pattern into a field decision.

A good match does not by itself prove efficiency, useful takeoff angle, common-mode control, or guaranteed field performance. Use the complete governed record and verify the installed system.
