Terrific Technical Information Source

[NZ0I]

I haven't mentioned this web site before (I don't think), but it is quite remarkable.

Follow the link to From Transmitter to Antenna: HF power transmission theory and practice.

If I had access to that kind of text when I was a teenager, it might have changed my life. It dispels many myths, and clarifies many mysteries. It isn't a light read, but it is remarkably readable.
