Robert 11,
THE LOOP ANTENNA ELEMENT :
The Loop being a Square/Rectangular Shaped Loop completes the
Circling of the Room around the Four Walls. Both Ends of the Loop
come together at some point on the Wall or at a Corner of the Walls
near the Ceiling and are connected to a Pair {Two} Parallel Wire
Feed-in-Line that goes down to the Radio's Antenna Input.
THE FEED-IN-LINE :
The short vertical Feed-in-Line for this type of In-Door {In-the-Room}
Loop Antenna is usually a Pair {Two} Parallel Wires.
* 300 Ohm TV type Twin Lead works well as a Feed-in-Line
for this type of Loop Antenna.
* Speaker Wire also can be used; either flat or twisted will work.
* The basic wire used to make the Wire Loop Antenna Element
can be continued as a single piece from the Radio up the Wall;
around the Four Walls; and down back to the Radio. If this is
done then it is recommended that the short vertical parallel run
has the two Wires Twisted together.
* A piece of Audio Coax Cable can also be used; especially if
the Radio uses an 1/8" Mono Jack for the External Antenna Input.
WANT A BIGGER LOOP ANTENNA - PUT IT IN THE ATTIC :
[ When an Out-Side / Out-Doors Antenna is NOT Permitted. ]
KISAP: I recommend using TV type Antenna Parts for most
"In-the-Attic" Antenna installations.
* 75 Ohm Coax Cable for the Feed-in-Line for Household
'man-made' Noise RFI/EMF Reduction.
* TV 75 Ohm to 300 Ohm Matching Transformer (Balun) for
Noise RFI/EMF Reduction and AM/MW Band Signal Reduction.
* TV 300 Ohm Twin Lead for the Wire Antenna Element
50-100 Feet -or- 90 Feet of Insulated Hook-Up Wire.
* "F" Jack to 1/8" Plug (1/8" Mono-Jack Adapter)
RadioShack Catalog # 278-257
