Ham Bands

mcnanovna prompts accept ham band names as shortcuts for frequency ranges.

Usage

In prompts:

calibrate(band="2m")
analyze_antenna(band="20m")
measure_antenna_range(band="70cm")

Or override with explicit frequencies:

calibrate(start_hz=144000000, stop_hz=148000000)

NanoVNA Frequency Limits

ModelMinMax
NanoVNA-H50 kHz900 MHz
NanoVNA-H450 kHz1.5 GHz

Bands outside these ranges can’t be measured directly.

Harmonic Measurements

For bands above the VNA’s range, harmonics can sometimes be used:

  • 23cm (1.2 GHz) on NanoVNA-H: Measure at 1/3 frequency (400 MHz) and look for harmonic response

This is imprecise but can give a rough idea of antenna behavior.

Band Plans

These presets cover the full amateur allocation. Actual band plans vary by country and license class. Consult your local regulations for permitted frequencies.
