Antenna models, NanoVNA and path planning
Design an antenna, measure it with a NanoVNA and plan the radio path it will be used on. Every design is solved rather than looked up, and every model is checked against the program it was ported from.

What it does
Match it and build it
Tune by hand or with the optimiser, synthesise an L, pi, T or stub match from standard parts, and get a cut sheet, a drawing and the feed detail.
Measure it
Drives a NanoVNA-H or H4 over USB with SOL calibration, SWR, return loss, Smith chart and cable de-embedding.
Plan the path
Terrain at 30 m resolution, Longley-Rice point to point, broadcast coverage maps, and HF circuit reliability by hour and band.
