// A friend experimented with various top-loading schemes. To
evaluate the results he made field-strength measurements. His findings
were that various top hats make a change in the reactance of the anrenna,
however, they did not make a change in observed field strength. My guess
is that this means that top-hats affect matching, but they do not much
increase radiation resistance.
