Near Vertical Incidence Skywave Propagation
If you need reliable region-wide HF communications, please consider a Near Vertical Incidence Skywave Antenna. In this video from Michael Martens (KB9VBR), we get an excellent introduction to NVIS and the antennas that can fulfill this role. NVIS HF antennas are perfect for regional and statewide emergency communications, providing strong signals up to almost 300 miles (480 km).

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.
