Would a matching balun enhance reception with the subject antenna?
If so, which? I see rfjunkie (eBay) has lots of different ones.

ABOUT - The AOR LA380 WideBand Active Loop Antenna
http://groups.yahoo.com/group/Shortwave-SWL-Antenna/message/6035

Since the AOR LA380 WideBand Active Loop Antenna accepts
a BNC Plug; it should already have a 50 Ohm Output Impedance
and therefore should not need any Matching Transformer. It can
be directly connected to your Radio Receiver.
http://www.aorusa.com/la380.html

Per Grove Enterprises the AOR LA380 Wideband Active Loop Antenna
has an Impedance of 50 Ohms
http://www.grove-ent.com/LA380.html

Per LA380 Leaflet (PDF Format) the Impedance is 50 Ohms

LA380 - Short Wave High Performance Table-Top Active Loop
Aerial, {Antenna} usable range : 10kHz - 500MHz
http://www.aoruk.com/direct/la380.htm

WHY NOT THE WELLBROOK ? ? ? ALA 1530 :
If you are in-fact considering the AOR LA380 WideBand Active
Loop Antenna : Then you should also be considering the
WellBrook Active Loop Antenna Model ALA 1530 150kHz-30MHz
which is a One Meter Diameter Aluminium Loop for Longwave,
Medium Wave and Shortwave.

The LA380 is probably a fine antenna, but it's an indoor antenna.
That's why I'd suggest that you consider a Wellbrook loop that you
could locate outside your home, even if it's only on a balcony or
patio.

Sanjaya,

Thank you.
I was intrigued by the 1 foot diameter of the LA380.

Sanjaya - And One Foot is all you get [.]
About 113 Sq In of Signal Capture Area (Aperture)

The WellBrook at about a Meter Diameter is larger.
About 1217 Sq In of Signal Capture Area (Aperture)

"Build - Your - Own" Loop Antenna

A GreerTech RG8 Coax Cable Loop Antenna used with an Active
Pre-Selector could be a low cost 'better radio reception'
answer instead of the with AOR and WellBrook WideBand Active
Loop Antennas.


A "GreerTech" Coax Cable {Shielded} Loop Antenna
Thirteen Foot (13') RG8 Coax Cable Loop Antenna Element with
a Four Foot (4') Diameter and a Three Foot (3') Feed-in-Line
with PL-259 Plug; for a Total Length of 16 Feet .
LOOP INFO => http://tinyurl.com/8k7o6
Has a Signal Capture Area (Aperture) of about 1808 Sq In
and can be used with many of the MFJ Active Pre-Selectors
MFJ-959; MFJ-1020; MFJ-1040; MFJ-1045; etc to provide an In-Door
Low Noise Loop Antenna to Null-Out many 'local' Noise Source.

Hey,I am going to read up on that GREERTECH Antenna.I assume it will
work for my old beat up Goodwill radios?
