Ham Radio 360: NVIS Near Vertical Incidence Skywave with Ed Fong WB6IQN

What is N.V.I.S? I hear it all the time; but for whatever reason, like most, I have a hard time putting it to words.  So I found us someone that could explain the theory behind the propagation, and his name is Edison (Ed) Fong-WB6IQN.


Ed helps lay out the theory of N.V.I.S in ways that even I can understand!  We discuss N.V.I.S and it’s practical applications for everyday use as well as in an EMCOMM Situ.

As we continue our antenna chat with Ed we begin to learn about his wildly popular J-Pole antennas.  From Dual-Band roll-ups to Tri-Band verticals, Ed and his students have been helping hams get on the air for years!

  1. I was listening to the podcast on the way to work and said, “I gotta git me one of them Ed Fong antennas.” The Ebay site said there were only ten left, so I immediately pushed the purchase button, but it wouldn’t let me buy the accompanying 50ft of RG8X. I quickly looked back at the antenna, and it said to call a number to request the cable. Now, it’s 7:15 am in New Orleans, and this scratchy voice answers on like the fourth ring. It was ED FONG, and I woke him up at 5 in the morning! Ugh, very embarrassing. He was nice about it though Sorry.

    “This is probably one of the best detailed descriptions of NVIS! Where else did you hear it should only be just off the ground? Kudos to 360!”
