Ham Engineeringv1.1.0

What changed

• New featureAdded a global Design Frequency field that synchronizes across all antenna calculators.
• UXAdded band edge indicators to help users select specific operating frequencies within a band.
• UXImplemented persistence for chosen band and frequency settings between app sessions.
• UXMaintained individual frequency fields per calculator for independent fine-tuning.

Original release notes

Enter the frequency once.

- Antennas -> Calc now has a single Design Frequency at the top of the page that fills in every antenna calculator below it: half-wave dipole, quarter-wave and 5/8-wave verticals, ground-plane radials, end-fed half-wave, random wire, full-wave loop and the 3-element Yagi. Pick a band to load its center frequency, or type any frequency yourself.
- The band edges are shown under the field, so you can nudge the frequency to the part of the band you actually operate instead of accepting the middle of it. This matters most on the wide bands - on 160 m the band centre is over two metres of wire away from where a CW dipole should be cut.
- Each calculator keeps its own frequency field, so you can still tweak a single antenna without disturbing the rest.
- The dipole k-factor and the random-wire length stay per-panel, because they are not frequency.
- Your chosen band and frequency are remembered between sessions.
