## Description

RF Calculator Pro is a comprehensive utility designed for RF engineers and ham radio enthusiasts, providing a wide range of calculations, conversions, and reference materials essential for radio frequency work.

Features include electromagnetic wave calculations (wavelength, frequency, period), resonance computations, propagation delay analysis, and radiated power assessment relative to VSWR. The app supports critical RF link functions like free space path loss, link budget evaluation, and Fresnel zone calculations.

Base station engineers benefit from transmission line analysis, effective radiated power calculations, and antenna down-tilt parameters. Radar-related computations such as power density and maximum range are included. The tool also offers detailed loss calculations like VSWR, reflection coefficient, and return loss.

Various converters assist with power, voltage, current, field strength, and distance measurements, making this a versatile solution. Additionally, it provides extensive reference resources including RF spectrum, amateur bands and Q codes, NATO phonetic alphabet, and common abbreviations, making it a vital tool for professionals and hobbyists alike.
