 Radio wave propagation describes the way in which radio waves travel from one point to another.  As we saw in the previous page, radio waves (like light waves) have polarization and are affected by the phenomena of reflection, refraction, diffraction, and scattering.  As we'll see next, these give rise to different ways that the signal can propagate through the atmosphere.  Radio wave propagation describes the way in which radio waves travel from one point to another.  As we saw in the previous page, radio waves (like light waves) have polarization and are affected by the phenomena of reflection, refraction, diffraction, and scattering.  As we'll see next, these give rise to different ways that the signal can propagate through the atmosphere.

-Here's a map of [[http://www.spacew.com/www/fof2.html |MUF]] that's updated regularly.  You can think of this as a "weather map" for ham radio.
