Dipole Cut Offline

Dipole Cut turns a target frequency into a field-ready antenna cut list—leg lengths, total wire, VF-corrected span, trim notes, and SWR history—on one offline card built for amateur radio operators. Open the app and land on a fullscreen antenna-span: a clear horizontal center-fed wire diagram with live left and right leg lengths, total span, and feedpoint marker. Dial MHz, set velocity factor, and watch half-wave dipole and quarter-wave lengths update instantly in metric or imperial with mm/inch precision. Built for real builds, not desk theory: • Velocity-factor dial plus seeded wire and coax presets (bare copper, insulated hookup, RG-58, RG-8X, ladder line) applied to the span in real time • HF/VHF amateur band quick-picks that snap frequency to common allocation centers and recalculate the whole span • Trim worksheet: planned cut, actual remaining length after each snip, and running delta versus target • SWR checkpoint log per project (frequency, reading, notes) kept beside the active span • Named antenna projects with local persistence—switch builds without losing VF, trims, or history • Element breakdown: total wire needed, each leg, end-insulator allowance, and center gap • Starter library (40m inverted-V, 20m flat-top, 2m ground-plane radials) editable as new projects • Plain-text cut summary via the system share sheet Everything runs offline-first. Units, default VF, and last-open project stay on device. No account required to cut wire in the field. Whether you are hanging a 40m inverted-V or trimming a 2m ground-plane, Dipole Cut keeps frequency, velocity factor, cuts, and SWR on one surface so you leave the bench with numbers you can trust.
