For Shortwave Listening (SWL) what you would spend on an
Active Antenna; you could buy a good 'passive' Wire Antenna.
* Your Location {Region} and Weather can be a Factor in
your choice of Antennas.
* The RF Environment {Noise} of your Location {Neighborhood}
also can be a Factor in your choice of Antennas.

1 - Two Major Determining Factors would be :
* The Size-of-the-Area {Space} that you have to put the
Wire Antenna up in; and the relative noise of your location.
- - - - - vice - - - - -
* The Distance-Away-from the Home and other Sources
of Noise that you could Locate the Active Antenna.

2 - Here are a few Good "Out-Side" 'passive' Wire Antennas
for the Shortwave Listener (SWL) : {Sized - Big to Small}
* Alpha Delta DX-Ultra Antenna
http://www.universal-radio.com/catalog/sw_ant/3377.html
* Antenna Supermarket Eavesdropper SWL Sloper Antenna
http://www.universal-radio.com/catalog/sw_ant/0013.html
* * Par Electronics EF-SWL Antenna - Rigged as a
15 Foot Vertical by 30 Foot Horizontal Inverted "L"
{Low Noise} Antenna with Coax Cable feed-in-line.
http://www.grove-ent.com/ANT8.html
http://www.universal-radio.com/catalog/sw_ant/2205.html
* RF Systems Mini-Windom Antenna
http://www.universal-radio.com/catalog/sw_ant/3575.html

3 - Here are a few Good "Out-Side" Active Antennas for
the Shortwave Listener (SWL) : {Priced - High to Moderate}
* Dressler ARA60S Active Antenna
http://www.universal-radio.com/catalog/sw_ant/4061.html
* RF Systems DX-10 Professional Active Antenna
http://www.universal-radio.com/catalog/sw_ant/2868.html
* * McKay Dymek DA-100E Active Antenna
http://www.universal-radio.com/catalog/sw_ant/0328.html
* LF Engineering H-800 Skymatch Active Antenna
http://www.grove-ent.com/ANT15.html
* MFJ-1024 Active Antenna
http://www.universal-radio.com/catalog/sw_ant/1132.html

Most of these are considered to offer Full Spectrum Coverage of
both the Medium-Wave and Shortwave Bands : 500 kHz - 30 MHz.

FWIW - As time goes on you may wish to have both an
Out-Side Wire Antenna and an Active Antenna as a "Pair"
of Antennas to Choose from for a variety of Shortwave
Listening (SWL) needs.

RHF, I'm surprised you didn't mention the "Mini Whip".

Steve,

PA0RDT-Mini-Whip {Active} Antenna - Inch-per-Inch - It Works !

David - The Par Electronics EF-SWL Antenna

http://www.grove-ent.com/ANT8.html
* Gives good all-around Shortwave Band reception and
works well on the AM/MW Band Antenna too.
http://www.universal-radio.com/catalog/sw_ant/2205.html
* It is no more complicated to install then most
small Active Antennas.
* Active Antennas need to be installed properly and
in the right location. Otherwise they can be great
Noise Amplifiers and make Radio Listening a pain.

- I'm away from any strong local signals and get really
- good service out of an MFJ-1024 on my bedroom radio.
- I can hear KOMO 1,000 very reliably every night and
- I'm 3 states away.

David - The MFJ-1024 Active Antenna was on the list
of Active Antennas that I provided.
http://www.universal-radio.com/catalog/sw_ant/1132.html
* For many who can not have a very 'visible' Antenna
small Active Antennas like the MFJ-1024 do a very
good job in letting them hear what they want to hear.
* The only feature of the MFJ-1024 that I do not like
is the Telescoping Whip Antenna.
* * I would replace the short Whip Antenna with a
solid CB Whip Antenna mounted on a piece of 21
Foot Top-Rail and 50 Foot of Coax Cable to get it
away from the House and out-side Up-in-the-Air.
* * Small Active Antennas like the MFJ-1024 some
times can be used In-Side the Attic with a Pair of
Perpendicular One-Metre Diamond Wire Loops.


and that's my view from the far side of . . .
the antenna wire - iane ~ RHF

This is no different than any other wire antenna with a coax matcher.

I have a random wire. A random wire with an MLB. And the MFJ-1024.

I posted my observation.

I don't appreciate your Doctor Bronner on Acid replies. They are
anarchy and they are more confusing tha helpful.

You have issues.

I have a Dymek Stoner DA100E active antenna, indoors. It works fine,
doesn't take up much space, but a full size outdoor wire antenna
provides stronger, louder reception of signals.

A big wire antenna is cheaper, the active antenna is more convenient;
take your choice.

The Stoner and the MFJ-1024 are essentially car radio antennas. They
are omnidirectional and vertically polarised. These can be
advantageous attributes sometimes. The more antennas the merrier.
