Find out why you want to keep you ears open for this phenomenon on today's podcast. What You Need To Know Most VHF and UHF reception is done via line of sight. Another form of radio propagation is ground wave, which follows the earth's contours. Radio waves that use the earth's ionosphere to further propagate are cause for excitement in the VHF and UHF Spectrum. The ionosphere is made up of several distinct layers. E-skip or Sporadic E happens when the radio waves are reflected back to earth by the unusually ionized the atmospheric gases in lower E levels. Weather can also affect propagation and this is called tropospheric ducting Find out more about Skip, Ducting, and Propagation on today's podcast.
