RF Calculator
Calculators:• Wavelength• Free space path loss• Attenuators• Link budget • Resonance• VSWR• Reflection coefficient• Return loss• Mismatch loss• Percentage ERP• Transmission line• EIRP/ERP• Fresnel Zone
Converters:• Power (dBm, Watt, dBW)• Voltage (V, dBV, dBµV, dBu)• Current (dBµA, dBA, A, µA)• Terminated (dBm, dBµV, dBµA, V)• Field strength (dBµV/m, V/m, dBmW/m², dBµA/m, W/m², dBpT)• Distance (cm, m, in., yd, km, mi.)
Reference:• Frequency bands (ITU)• Amateur bands• Amateur band plan
- IARU region 1• Amateur Q codes• Phonetic alphabet (NATO)• Decibel suffixes• SI unit prefixes

Excellent app! Intuitive, fast and simple.
The calculator does not accept a decimal point without a number before it. Try entering : point three!
Very cool when one is distracted from clear thinking
Forced close after open the app everytime
Nice sw, but don't have landscape mode
Super helpful and nicely designed
Very useful app and well laid out.
Excellent and useful.
Excellent ,thank you
Excellent, thank you !
thnk you for this app
Quality app for engineers
It's very nice RF calci. Try to provide similar on microwave app.
Great tools! Great app!
Very good applications for professional
I used it every day, it is great
Very handy reference tool
Very nice and useful tool. Thanks and wide compliments !
Great work.... As a suggestion. You can include some q code teaching sessions...
Great ap. Nice job. ... maybe could you add air core inductor calculator?
Easy to use for what I know, and so much more than I know how to use available. Best compact calculator converter app I have seen in a while.
This is very useful toll for RF Technicians and RF Engineers. Easy explained by you. With the help of this tool I have learn so many concept. Thanks.
Nice UI, clean, straight forward and...no ads. Really recommend for anyone working with RF systems be it professional or ham radio operator.
Clean, efficient, very useful and it happily runs on older Android versions. It had more functions than I knew what to do with. Does resonance calculations, SWR, unit conversions and much more.
From what I can see, and have done with the app, this is a GREAT APP. It's great for "Ham" operators and their need to figure antennas and equipment for both transmit and receive. Thanks
Very easy to use. It has all what i need for unit conversations.
Would be nice to see band plan for other IARU zones.
Thank fer this type app. Very useful for HAM radio stations.
It is easy to use and quite handy (and there are no ads)
Very useful reference and utility app for anyone beginning on short wave listening. Easy interface and useful functions.
