Coaxcraft: Antenna Bench

About Coaxcraft: Antenna Bench

Coaxcraft is an offline experiment notebook for amateur-radio and RF builders comparing real antenna and feedline revisions.

Keep antenna revisions, analyzer sweeps, feedline identity, trim steps, mount context, weather, and observed results in a private experiment lineage.

KEY FEATURES
- Antenna, revision, mount, and feedline cards
- Frequency, SWR, impedance, and sweep observations
- Wavelength, matched-line, and mismatch-loss arithmetic
- Controlled trim and configuration comparisons
- Weather and installation context
- PDF antenna experiment brief
- Optional local photos through Apple's Photos picker
- Local PDF project brief
- 230 original offline reference plates
- No account, ads, analytics, tracking, subscription, or network requirement

Coaxcraft is a documentation and idealized RF arithmetic tool. It does not connect to analyzers or radios, measure radiation or efficiency, approve an antenna, assess RF exposure, lightning or structural safety, or replace license conditions, calibrated instruments, manufacturer data, and qualified RF guidance.
