[ARRL-OK] LINK to info: Near Vertical Incidence Skywave (NVIS)

[Mark Conklin]

I located a link to the mentioned White Paper from DX Engineering 
about building a NVIS type antenna.  

Go to the DX Engineering link page and click on their link to open up the White Paper.

Hi, Mark. 
 
You probably know by now that the ARRL-OK list won't accept attachments of any kind.  Do you have a URL link to the document?

Attached you will find a interesting White Paper from DX Engineering 
about building a NVIS type antenna.  Thanks Lloyd KC5FM & Ron KB5UVC for passing this along.
 
Near Vertical Incidence Skywave (NVIS) is a propagation mode which uses high angle radiation to send signals almost straight up to be reflected back to Earth for very effective short to medium distance communications. This mode of operation makes itideal for in-state communications during disasters or other emergency situations. The military has used NVIS techniques for decades to provide short haul communication with other units on the ground.
