A Graphical Comparison of Distance Range for Radio Types and Stations

"How far will that radio go?"
"What type of radio should I get for most range?"

These simple questions often lead to complex answers because so many factors influence the distance of radio communications.

To simplify, the following charts show how many miles you can usually communicate over normal terrain in suburban or rural areas with different types of radios, power levels, and station configurations.

The graphs compare the most commonly available 2-way radios such as ham, CB, FRS, MURS, and GMRS.

Some radio gear advertisements tout the maximum possible distance in perfect conditions, an often misleading specification. In the real world, people want to know the normal dependable average range of a radio.
