Ohms dB VSWR Coax Field Calcs
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Get the exact numbers you need right when you need them—on the bench, in the field, or at the job site.
Electrician RF Power Toolkit delivers a rugged, practical suite of calculators designed for the daily realities of electrical engineering, radio frequency work, and electronics repair. No fluff, no internet dependency, and no hunting through unrelated consumer tools. Just clean, fast, and precise calculations paired with a built-in notepad to log field measurements before moving to the next task. This gives electricians, service techs, RF hobbyists, electronics builders, and bench technicians a practical set of calculators for everyday electrical and radio work.
It is made for the jobs where you need a number now: checking a circuit, sizing a resistor, comparing power levels, working through a coax problem, checking VSWR, estimating reactance, or saving a field note before you move on.
