How big a hat? 10 gallons?
But only if we are CowBoys (CB) :-)
As far as I can see, the radius of a capacity hat must be the difference between the vertical's length and the 1/4 wave length of the desired band? AIUI, the waves progressing in all directions in the capacity hat cancel each other's fields resulting in no radiation, but the transit time to the edge of the hat and back act as the required element extension. |
