RF Calculator Pro is a utility application consisting of various calculations, conversions and reference tables.

Radiation:
•	Electromagnetic wave (wavelength, frequency, period)
•	Propagation delay (distance vs. time)
•	Resonance (frequency, inductance, capacitance)
•	Radiated power (vs. VSWR)
•	Air core inductors (inductance, turns)

RF Link:
•	Free space path loss (loss, distance)
•	Link budget (RSSI, fade margin)
•	Fresnel zone (1st, max, 60%, Er)

RF Base Station:
•	Transmission line (Tx, Att, Pout)
•	EIRP ERP (effective radiated power)
•	Antenna down-tilt – angle (angle, distance)
•	Antenna down-tilt – coverage (inner & outer radius)

Radar:
•	Power density (W/m²)
•	Maximum range (distance)

Losses:
•	Attenuators (Pi, Tee)
•	VSWR  (voltage standing wave ratio)
•	Reflection coefficient (Rho)
•	Return loss (dB)
•	Mismatch loss (dB)

Converters:
•	Power (dBm, Watt, dBW)
•	Voltage (V, dBV, dBµV)
•	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:
•	RF spectrum (ITU)
•	Amateur bands
•	Amateur band plan – IARU region 1
•	Amateur Q codes
•	Phonetic alphabet (NATO)
•	Decibel suffixes
•	SI unit prefixes
•	Abbreviations
