Which portion of this antenna is the radiator? Is it the portion below
the coil or the entire antenna?

The part of the antenna that radiates the most
is the part below the loading coil. On my HS-1600,
that section is 3 feet long. If you want to
dramatically increase your radiated power, add
another three foot section under the existing one.
Since you don't have to contend with the 12.5 foot
mobile antenna limit, make that bottom section
below the coil as long as possible.
