Discontinued.
Universal Radio sold out.


But lately Ebay seller named buyfromjapan is shipping them to USA in
less than a week, $89 + 15 shipping. If you click his 100% feedback,
then you will see all the happy loop buyers' praise!


e.g.

It's very good.


If you don't have one; check it out . ..


Wasa Up !


For Shortwave Radio Listening (SWL) the Sony AN-LP1
Active {Shortwave Only} Antenna works very well with
the Sony ICF-SW7600GR AM/FM Shortwave Radio as
a "Travel Kit" for the Hotel Room, RV'ing or Camping
when you are On-the-Road :

imho - both are worth the money
and together they are great ~ RHF

I've had two of them, one died, the other one I sold. I thought the
first one had a problem, so I stupidly bought another one. It wasn't any
better.


Not much good except as a noise magnet, picked up every light switch,
dimmer, transformer, furnace igniter and A/C compressor relay on the
block. The neighbor's furnace igniter made all kinds of racket on the
AN-LP1, but was barely audible on any of my other antennas. The other
neighbor's family room and kitchen lights made a huge SNAP as they were
turned on and off(They were right below the LP1). The slinky dipole,
that blew the Sony out of the water, in both lack of noise, and with
much better signal strength just heard a moderate "click". That slinky
was the best antenna I ever had, I hope the new one is half as good.
from 14MHZ on down, it was amazingly good, it was much better than my
Alpha Delta Sloper.


I used the AN-LP1 as a backup antenna at first, and later on, as an
antenna for one of my 5 SW desktops I had at the time. Out of a Slinky
dipole, a sloping Windom Dipole, both outside and high up in the air, a
dipole in my attic about 10' off the ground, and a CB antenna with the
shield pulled off at the receiver,


- the AN-LP1 at 40', was a distant fifth place.


I'm back to 5 desktop receivers, and I'm not messing with
another active antenna this time. Especially for 105 bucks. That will
buy a LOT of coax and wire for making my own antennas. I bought a metal
CB antenna for the higher freqs. A CB antenna is very useful for Utes
above 15MHZ or so. With the shield pulled, it's not bad anywhere.

BDK - Please Clarify ~ RHF

-?- Are you talking (writting) about the "Indoor"
Sony AN-LP1 Active {Shortwave Only} Loop Antenna
http://www.universal-radio.com/catalog/sw_ant/3676.html
http://cgi.ebay.com/_W0QQitemZ130116236247
* Which uses a small 19" Cloth covered Loop Element

.
-?- Or the Sony AN-1 "Outdoor" Active Whip Antenna
which covers the LW + AM/MW and Shortwave Bands
http://www.universal-radio.com/catalog/sw_ant/2206.html
* Which uses a 59" Telescopic Whip Antenna Element
and Remote Head Unit plus Coax Cable and Desk-Top
Control Unit.

I was talking about the outside one, sorry.

BDK - That was the impression that I got
when you wrote " the AN-LP1 at 40' " ~ RHF

Using a 102" CB Whip Antenna with the
Sony AN-1 instead of the 59" Telescopic
Whip Antenna can improve it some what.

Better is using a Pair of Diamond Loops made
of Wire that are 24" on the Side. The Diamonds
are set perpendicular to each other in an "X".
All the Wire Ends come together at the Whip
Mounting Stud. Wood or Plastic is used as
the Cross-Arms (24") of trhe Loops. And the
Loops are suspended from the Top-Apex with
the AN-1's Head Unit hanging at the bottom.
The two same size Diamond Loops can be
scaled down or scaled up by simply keeping
the Sides and the Cross-Arms the same length :
12" Sides by 12" Cross-Arms = 21" High Diamond
18" Sides by 18" Cross-Arms = 31" High Diamond
24" Sides by 24" Cross-Arms = 42" High Diamond
30" Sides by 30" Cross-Arms = 52" High Diamond
36" Sides by 36" Cross-Arms = 63" High Diamond
Some use a bare solid Aluminum Ground Wire for
the smaller Diamonds; and others use Insulated
Stranded Hoop-Up Wire for the Larger Diamonds.

IMAGE - Look at the Top of the RF Systems DX-One
Professional Mk II Omni-Directional Active Vertical
Receiving Antenna for an Idea what the 'shape' of the
Two Diamond Loops looks like.

FWIW - There are Theories about "The Why" of
using the Two "X"ed Diamond Loop Elements
-vice- The Single Vertical Whip Element
-but- These Theories are beyond me.
And- The Reason for the use of a Whip Element is
that it is simple, practical, durable and best value.

as always more than you wanted to know ~ RHF

It was the noise it picked up, the signal strength wasn't bad, just the
snapping, popping, and buzzing. I actually stuck a hunk of wire on it
after the whip disappeared and it made little difference. I wish I had
the ambition to build a TFD antenna, a friend had one for several years,
and it was great, very quiet, and in the winter, was almost spooky with
the lack of background noise. Amazingly weak SSB and RTTY signals could
be copied 100% on it. The one B&W or whoever it is that makes one is
just too expensive and needs some upgrading to last.
