ECOM HF Antenna

Interesting reading.

There are many times when an ARES or RACES group will need to provide
communications for a served agency over terrain that is not inducive to
those communications. Such as many of the areas in Colorado where our most
known feature, mountains, heavily restrict VHF/UHF communications. As such
we, as an organization, have taken to using the Near Vertical Incident
Skywave (NVIS) antenna on 40M and 75M (we will soon see how 60M works
also).
