How Antennas Work?

Boy is that a good question. In 1960 the U.S. Air Force tried to teach me how to repair heavy ground RADAR sets and I have been trying to learn ever since.

As you can see from my shack and antennas page I love to build antennas, especially the Off Center Fed (Windom). The problem is the more I read, the more antennas I build, the more confused I get. The result is this page where I will lump together the interesting antenna links I find on the internet. These will be perfect references for you if you HATE math or cannot do same like me.

More than 468/f. Allows you to calculate correct
wire length after testing your first try. I use it to
help build all my dipoles.
