App Description
Antenna+ is the must-have toolkit for amateur radio operators and RF hobbyists. Whether you're designing a dipole, tuning a vertical, calculating feedline loss, or planning an HF/VHF/UHF deployment, Antenna+ gives you accurate formulas and instant results. Key features include antenna-length calculators (dipole, inverted Vee, quad, bazooka, and more), frequency-to-wavelength conversion, VSWR and ERP calculators, RF conversion helpers, horizon visibility and solar calculators for propagation planning, plus signal utilities such as DTMF decoding/keying and Morse/PSK31 tools. The interface is optimized for both iPhone and iPad comes with Retina-ready icons and an integrated manual, and is built with test targets included for reliability.
Benefits:
- Quickly design and size antennas for HF, VHF and UHF bands
- Reduce trial-and-error deployment time with VSWR and ERP calculations
- Plan best operating windows using built-in solar/dawn/dusk and horizon visibility tools
- Decode DTMF tones and use the DTMF keyer for tone generation; includes microphone access for decoding
- Find quick reference formulas and illustrated for field use
