What website(s) are good for designing a wifi antenna?
Just out of curiosity,
What websites do you folks find to be the most useful in your design of an original wifi antenna to increase your signal strength? (ie. theory, math, hardware, instructions, first sources) As a ham radio guy, I know some (but not enough) and I know enough to know that the measure three times, check the math, and cut once approach is best with any antenna.
