Small utilities that earn their keep
Tools
Tools stay lightweight, understandable, and tied to actual operating decisions.
What will show up here

- Small support tools that solve one real bench or field problem
- No accounts, no dashboards, and no mystery math hidden behind a button
Who this should help
- Operators who want a quick estimate before heading to the workbench
- Builders who need simple support tools rather than giant software suites
- Readers who want the formula and the result in the same place

Center-Fed Dipole Calculator
The first tool estimates starting lengths for a center-fed half-wave dipole using the common approximation of 468 / MHz for total length in feet.
Start with a target frequency, or estimate how much to trim, fold back, or add after measuring a real antenna.
