For One and All,

Do-It-Yourself - Build and FM Loop Antenna Project -and-
Works for both Analog or Digital FM Radio Broadcasting
FM LOOP =http://www.wryr.org/Antenna_instruct.../message/12886

Basically a Square "Quad" Loop Antenna design a little
under Three Foot (36") on the Side :
FM QUAD =http://www.wryr.org/Antenna_instructions.pdf

Single Turn Hook-Up Wire Antenna Element

300 Ohm TV type Twin Lead feed-in-line

Simple "X" Diagonal Wooden Frame

Mount it In-Doors either :

Flat Horizontally for all-a-round Omni-Directional FM Radio
Reception.

On-the-Edge Vertically for Point-and-Shoot FM Radio Reception.

PLUS - If you can not have an Out-Side External Antenna
for your Shortwave Radio -and- You need and Antenna that
you can Store and put away when you are not using the
Shortwave Radio : Then this simple Loop Antenna can be
used with some success to Listen In-Doors and Position
the Loop Antenna Element to Null-Out some of the Noise
within your House. *Lays Flat and [Hides] nicely behind
a Desk, Bookcase or Curtains when not in use.
SWL LOOP =http://www.wryr.org/Antenna_instructions.pdf

NOTE - These small Single Turn Loop Antennas usually
work best with the HI-Z {500 Ohm} Terminals found on
most Shortwave Radios.

from fm to shortwave it's doable - iane ~ RHF {pomkia}

A MODIFICATION to this Small Loop Antenna for Shortwave Radio
{Small Loop Element that is Square Shaped and Under 3-Foot}
Listening (SWL) is to use 300 Ohm TV type Twin Lead for the
Loop Antenna Element.

SHORWAVE QUAD =http://www.wryr.org/Antenna_instructions.pdf

Twin {Parallel} Single Turns using 300 Ohm TV type Twin Lead
for the Wire Antenna Element for Higher Shortwave Frequencies.

-OR- Double {Series} Two Turns using 300 Ohm TV type Twin Lead
for the Wire Antenna Element for Lower Shortwave Frequencies.

ADD - A Four Terminal Block to make the Switch from Series
to Parallel and back as needed.

300 Ohm TV type Twin Lead feed-in-line

Simple "X" Diagonal Wooden Frame

that's all - iane ~ RHF
