Near Vertical Incident Sky Wave Propagation NVIS Antennas

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=fvZ7z-6wAy0.  This is post 2175 in a continuing series of simple ham radio antennas.

Michael Martens (KB9VBR) takes us through the theory, design, construction, and testing of NVIS (near vertical skywave) antennas.

These "cloudwarmer" HF antennas are perfect for state and regional communications, with signals reaching between 100 and 300 miles (162 to 486 km). 

As Michael explains, NVIS antennas are easy to make and can fill in communications gaps not covered by VHF/UHF repeaters:
"
Near Vertical Incidence Skywave Propagation is an effective form of HF communication for stations in a 100 - 300 mile range. Ideal for Emcomm, the emergency communicator should be familiar with the use of NVIS antennas and propagation.
