Radio range calculator

The range printed on the box assumes flat terrain and ideal conditions. Enter the band and the terrain, and you get a more realistic figure.

A hatótávot HÁROM dolog dönti el, és a watt csak az egyik — rendszerint a legkisebb súlyú. A másik kettő: hogy MILYEN SÁVON adsz, és hogy MI van közted és a másik között. Ezért nem lehet egy rádióra egyetlen kilométer-számot mondani.

The range is shown as a span, not a single number: a value to one decimal place would look more precise than radio can actually be predicted. Antenna height matters as much as the watts.

What it is good for, and what it is not

This calculator comes from the PrepperPapa app, where it is free too. The calculation runs in your browser: we send nothing anywhere and store no data about it.
