You can leave the internal antenna alone and augment it with a larger
external loop.  If you have seen the plans on how to build a tuned loop, and
have a air variable capacitor from an old radio, you can do that.  The loop
can be as simple as maybe 20-30 turns of wire wrapped around a 1' square box
and the ends connected to the two terminals on the capacitor.  Stick the
radio in the box so the turns are oriented vertically, and around the
front/back of the radio.  Tune for a peak.  Cheap, and effective.  The air
core wire loop would work better that way than the Quantum.  A lot cheaper,
too.

When you find some that aren't clear, drop a note in here..  Glad to help!
