Built for the Work
Record sweeps, estimate wavelength, line loss, mismatch loss, and delivered power, compare trim runs, and export complete bench notes offline.
One-time iPhone and iPad app
Coaxcraft: Antenna Bench
Keep antenna revisions, analyzer sweeps, feedline identity, trim steps, mount context, weather, and observed results in a private experiment lineage.
Actual App Interface
Ready When the Work Starts
Record sweeps, estimate wavelength, line loss, mismatch loss, and delivered power, compare trim runs, and export complete bench notes offline.
Core Tools
- 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
Private by Design
Coaxcraft has no account, ads, tracking, analytics, subscription, or developer-operated backend. Records stay on your device unless you intentionally export a PDF through the iOS share sheet.
Product Boundary
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.
