I really meant "half wave dipole", although the statement is still true as
written.

The input impedance of a 0.05 wavelength monopole, over a perfectly
conducting ground plane, is
0.836 - j1331. Using a shunt "L" series "C" matching network -- inductor Q
of 300 -- indicates a
network loss of 9 dB.
