Radio propagation categories. There are a number of categories into which different types of radio propagation can be placed. These relate to the effects of the media through which the signals propagate. 1  Free space propagation: Here the radio signals travel in free space, or away from other objects which influence the way in which they travel. 2  It is only the distance from the source which affects the way in which the field strength reduces.
Line-of-sight is the direct propagation of radio waves between antennas that are visible to each other. This is probably the most common of the radio propagation modes at VHF and higher frequencies. Because radio signals can travel through many non-metallic objects, radio can be picked up through walls. This is still line-of-sight propagation. Examples would include propagation between a satellite and a ground antenna or reception of television signals from a local TV transmitter.
