The project is to study radio propagation in the 40-m band in the ionosphere.

Weather conditions in the lower atmosphere can produce radio propagation over greater ranges than normal.

This is an index to articles about terms used in discussion of radio propagation.

It has practical importance because, among other functions, it influences radio propagation to distant places on the Earth.

The number of these free electrons is sufficient to affect radio propagation.

It has practical importance because it influences, for example, radio propagation on the Earth.

This particular version of the Hata model is applicable to the radio propagation within urban areas.

Chapman started his career with his work on radio propagation and the ionosphere.

The last three topics deal with radio propagation, aerials, and frequency measurement.

Ionospheric radio propagation has a strong connection to space weather.
