Hello Dave,
I was wondering about capacity hats. Don't know much about them or had
any experience with them. Will have a look on google.
Cheers

the cushcraft 40-2cd and the xm-240 use them just after the loading coil.
They can also be mounted at the tip of the elements. They use two 18-24"
long aluminum rods in an X configuration. More rods, or adding a wire
around the tips adds more capacitance.
