Understanding Near Vertical Incidence Skywave (NVIS)
This webinar explains why the "lost art" of HF is not only still relevant, but has been making a comeback in recent years, particularly in the area of both local and global communications. A central topic of this presentation is why much of the rebirth of HF is due to advancements in a wide range of fields, such as antenna design and digital modulation schemes, as well improvements in our understanding of propagation and how we can adapt to the challenges of propagation at HF. In addition to these topics, this webinar discusses how the performance and capabilities of HF direction finding / radiolocation have been improved in recent years and why DF has become an important enabler of HF as a modern communications technology.
