Ground plane reflection effects are an important factor in VHF line of sight propagation.
2.
However, this approach serves as well for line of sight propagation as for indirect reflected propagation.
3.
Microwaves are widely used for line of sight propagation; they cannot pass around hills or mountains as lower frequency radio waves can.
4.
Because of the line of sight propagation of UHF signals, experienced users consider such ratings to be wildly exaggerated, and some manufacturers have begun printing range ratings on the package based on terrain as opposed to simple power output.
