It is an intriguing idea for a top-loaded mobile antenna. One of the
problems with pure top loading is to keep the field of the coil
from encountering the top hat. A T-500-2 core would pretty much
confine the field to the powdered iron core so that it could be
mounted close to the top hat. Sounds like a good future experiment.
