The Radio's Whip Antenna
http://groups.yahoo.com/group/Shortwave-SWL-Antenna/message/15647
* Just What Is It ?
* Making It Work Better !
The Headphone's Lead and the Whip Antenna may be viewed
as a Dipole {Hertz} Antenna of sorts : Since they would
be of 'about' Equal Length.
http://en.wikipedia.org/wiki/Dipole_antenna
Back to the Radio and it's Whip {Marconi} Antenna
http://en.wikipedia.org/wiki/Whip_antennahttp://www.ycars.org/EFRA/Module%20C/AntVert.htm
The Whip Antenna is the Antenna Element and the combined
Electrical Circuity of the Radio is the Counterpoise
{Ground Plane}. Clearly the Whip Antenna is a much better
Antenna Element; then the Radio is an effective Ground
Plane. In effect the Radio's Ground Plane is all crumbled
up into a relatively small area.
-Note- This is considering the Radio itself {Stand-A-Lone}
Powered only by Batteries. [No AC]
Using another much Longer Wire with the Radio creates a
very effective Counterpoise to the Radio's Whip Antenna.
-IF- This Long Wire Counterpoise is Used -and- the Radio's
Whip Antenna is Collapsed or Removed -then- Things are
often reversed and the Longer Wire becomes the Antenna
Element and the Radio once again becomes the ineffective
Counterpoise.
Grounding the Radio itself : Grounding the Outer-Ring of
the Radio's Earphone Jack can also improve the Ground /
Counterpoise with respect to the Radio's Whip Antenna;
and thus can often cause an Improvement in the Reception
of the Radio.
ABOUT - Hertz and Marconi Antennas

Other "Observations" of Improved Radio Reception :
* Connecting an AC Power Cord and using AC Power
* Connecting an AC Adapter and using AC Power
* Connecting a Wire to the Radio's Whip Antenna
* Touching the Radio with your Hand
* Putting the Radio on a Metal : Desk Top , Shelf or TV Tray
HOW TO : Building a Simple Basic 'Mini' Dipole Antenna
for most '****table' AM/FM Shortwave Radios.
Buy an FM Folded Dipole Antenna the type made from
300 Ohm TV Twin Lead.
* Connect an Alligator Clip to one of the Leads of the
FM Folded Dipole Antenna
* Connect Rear-Barrel of an 1/8" Mono-Plug to the 'other'
of the Leads of the FM Folded Dipole Antenna {Remove the
Tip of the 1/8" Mono-Plug}
* Stretch-Out the FM Folded Dipole Antenna in the shape
of a "T" across/near a Window or on an Outside Wall
* Insert the Rear-Barrel-End of an 1/8" Mono-Plug into
the Radio's Headphone Jack
* Attach the Alligator Clip to the End of the Radio's
Collapsed Whip Antenna
IMHO - This 'Mini' Dipole Antenna usually out performs
the Radio's Whip Antenna and is a Easy-to-Use and a
very Trans****table "Travel Antenna".
TIP - This is also a Good {In-Door} "Storm" Antenna
when the Weather is bad and you do not want to Risk
Using an Out-Side External Antenna due to Lightning.
the antenna -allows- your radio to be . . .
