Description
The program Field Strength and Power Estimator calculates power flux density, electric and magnetic field strength from the transmitted power, associated frequency and gain of the transmitting antenna.
Additionally the input power into a receiver with 50 Ohm input impedance is calculated from the gain of the receiving antenna.
The program automatically converts power flux density into electric and magnetic field strength.
Depending on the transmitted frequency, various parameters influence the received power and field strength, such as non-line-of-sight propagation, changes in polarisation, reflections, and multi-path propagation affect the true values. Additionally antenna VSWR and cable losses have to be considered.
The program Field Strength and Power Estimator does not consider these impairments. It assumes conditions, that are close to the best possible theoretical values. This is why we say the program is an Estimator, not a Calculator.
This application is based on the application note:

Ratings and Reviews
Handy
This has been my go-to app in field strength and signal level calculation. Use it constantly as it is useful and convenient.
Perfect!
This tool is exactly what’s needed to estimate RF field strength at various power levels, distances and antenna gains. It’s very helpful being able to directly convert between the relevant units like dBm, watts, uV/m, etc.
Superbly done. Thank you!!
