Hello,
What is your preference with regards to frequency range, loop or
vertical whip, etc?
Why you prefer an active antenna instead of passive?
Some makers: DX Engineering, Wellbrook. If you like electronics,
there are various building plans on the web for both whip or loop
active antennas.
With kind regards,
Wim

.5 - 30 Mhz
"Due to high amplification, not recommended for shortwave portables
which tend to overload easily."

Sorry bout that... indoor whip is fine, telescoping is also fine. I'm
just researching right now to see what you all like...
Hello,
From the above I assume you have a portable (with or without external
antenna input).
With today's interference from electronic equipment, a simple outdoor
antenna may give better S/N ratio then the best indoor antenna. Most
portables have sufficient sensitivity to work properly with a passive
antenna.
A too large/long antenna may result in receiver overload. If so, you
will note a strong increase in noise like signals and reception of
same station at several positions on the dial (or frequency readout).
Longer or larger doesn't automatically means better.
If you need further info, don't hesitate to come back.

What radio are you intending to use ? Many receivers (even very dear
ones ) don't agree with Active Antennas due to insufficient (or
absent) pre-selection plus low dynamic range : 'anemic' front end is
NOT that rare at all .
OK so if you are using a Shortwave 'portable' Radio
and require an indoor Shortwave Antenna

What part of "discontinued" eludes you?
Support people who support you. Sony doesn't care about shortwave.

Thank you! I do have a couple Yacht Boy 400's with externals inputs so
yes i will consider your advice...
>MFJ makes a bunch of different ones.
Not a big mfj fan...
Thank you for your advice!..
I've had surprisingly good luck with them. The few "little black
boxes" I've purchased from them have given me years of mostly trouble-
free good performance.
I have a couple of Yacht Boy 400's for the .5 - 30 Mhz range...
I'll give em another look...
One other item I've tried and have had fun with is the Radio Shack
amplified shortwave antenna 20-280. Just a little plastic thing, but
it does the job. Again, it can pick up RFI so you have to find a
quiet spot for it - but as remote port-a-tenna it's a blast.
You're allowed to try to fix them; even if you destroy it in the process
you don't void the warranty. You can call the guy who designs the shit
and ask him questions (try doing that with Kenwood).
Man, if MFJ had been around when I was a kid my whole life would've
turned out different. They make some cost-effective fun stuff.
Dangerously close to the dreaded [rhymes with "shiny henna"]
YB 400 by Lextronics (now Eton) ? Good portable , I had the pleasure
of owning one a while ago . Very sensitive ,btw . They produced two
versions, afaik . Namely , YB400 and 400PE . Wouldn't recommend an
external preamp on either one . Passive antenna (space permitting )
will invariably bring in much better performance . Solar Cycle 24 is
warming up lately ,so it may not be needed at all .
The variable conrols they used were of dubious quality . Never seen
such low grade potentiometers ever, must be from the bottom of the
barrel . Had their dual time zone clock (2 side by side) where both of
them lost time immediately irrespect of the other ... Just hope they
improved their QC, had very bad experience with M-F-J in the past ...
I agree, I have to spray the pots quite often.
One of them froze or corroded internally so badly I threw the unit
into my parts box . And labeld the box appropiately : NFG .
Thanks! I will also consider this!..
Oh interesting, i didn't even know Radio Shaft made one... hmm...
Thanks!..
And that's Xactly what i've heard about mfj...
More like 90% returns ! That will sober up any self-respecting
businessman .
