Default Inductance of a solid disk

I'm wondering if he means "reactance" instead of
inductance. The reactance to ground is capacitive
for a solid disk.

Hello to all,

The context is this: We are discuting about capacitance hats.. It
seems that the name is confusing, since it adds inductance instead of
capacitance to an antenna.

So, since a solid disk adds inductance (the resonnant freq of the
antenna drops), we are looking for a formula to evaluate that
inductance (and then inductive reactance)..

BTW, why don't we use the name 'inductive hat'...??
