Tropospheric Ducting Explained

You've always been taught that VHF communications are line of sight and that the height of your antenna determines how far your 2m communication might go. So if I tell you that last week I spoke with a station that was 300 kilometres away on the 2m band you might be forgiven in thinking that I had managed to climb up most of the side of Mount Everest to around 7 kilometres so I could make my line-of-sight communications 300 kilometres away.

This week we find out how that works using a phenomenon called "Tropospheric Ducting".

Foundations of Amateur Radio is a weekly podcast about the wonderful hobby of Amateur or Ham radio. You can catch it on-air, on- line or on-demand. Check out iTunes by searching for my callsign VK6FLAB for your personal copy, or visit the website at http://podcasts.itmaze.com.au/foundations/
