That might not be a fair comparison, since the pattern might be quite
different with and without the resistors. To determine what fraction of
the applied power is dissipated in the resistors, simply click the Load
Dat button.

Just modeled the subject antenna as well as I can. Without the
termination resistors, the antenna has a gain of +6 dBi on 3.8
MHz. With the termination resistors, according to EZNEC, the
gain drops to -10 dBi, a difference of 16 dB.
