This is post 2388 in a continuing series of simple ham radio antennas.

Callum McCormick (M0MCS--the "DX Commander") has designed several successful HF antennas for radio amateurs. These antennas are price competitive with other brands, fairly easy to assemble and test, and produce excellent results.

In this video, Callum takes us behind the scenes and shows us the design and testing procedures for his current "Nebula eXtreme Multiband HF Antenna."

A thoroughly enjoyable look at antenna creation from start to finish.

Here are some of Callum's comments:

As I move to the "final push", I discuss the considerations including harmonics and practical problems involved with multiple elements and their tuning. We discuss element lengths, mechanical connections and hardware. Callum. #MNHR #YTB #HAMRADIO
