N.V.I.S. stands for Near Vertical Incidence Skywave. It is a propagation mode that allows for communication between stations at short to medium distances, typically between 0 to 300 miles. Ed Fong, WB6IQN, is an expert on N.V.I.S. propagation and shares his knowledge on the topic in this episode. He explains the theory behind N.V.I.S. and how it can be practically applied in everyday use as well as in emergency communication situations. In addition to discussing N.V.I.S., Ed also shares information about his popular J-Pole antennas, including Dual-Band roll-ups and Tri-Band verticals, which have helped many hams get on the air over the years.
