NEC-LIST:loaded dipoles

A way to "broadband" an antenna is to shunt the feed point with a resistor,
say 100 ohms for a dipole. The impedance presented doesnt stray too much over
a wide range of frequencies. Of course the coupling efficiency to space does
change, but this is not important if the ambient noise is greater than system
noise.
Such a "black box" was offered commercially a number of years ago.
