Face-to-Face Presentation: Understanding NVIS Propagation
January 22, 2026 @ 19:00 - 21:00

NVIS propagation, or Near Vertical Incidence Skywave, is a type of radio communication that allows signals to travel medium distances (up to 650 km) by sending radio waves nearly straight up into the ionosphere, where they are reflected back down to Earth. This method is particularly useful in areas where traditional line-of-sight communication is obstructed, such as mountainous regions.
Ron, N0IVN, will present this topic to us at our January Face-to-Face meeting. Come, learn the theory and how to put this in practice. What kind of antenna do you need to successfully do NVIS? What considerations should you think through before engaging in NVIS communications? Which HF frequencies are best for using NVIS propagation? How does NVIS help Emcomm as a resource in communications? Is NVIS better during the daytime or night time?
These questions and more can be answered by N0IVN. See you at the January Face-to-Face meeting. All are welcome to attend.
