I've got a Palomar magnetic balun sitting on my desk. Once I got the
Wellbrook, the magnetic balun became a paperweight.

I'm using the old ALA 100 and various home made loops. You need about
8ft of loop to make the ALA100 useful, though as a NDB direction
finder 4ft seems to work better. For shortwave DXpeditions, I've used
as much as 40ft in portable applications.

The thing about the ALA100 is you get a good piece of electronics that
allows hacking. That is, you make the loop. The other thing you notice
once you use a wellbrook is that the S-meter really isn't that
significant. Once in a while you will get a higher reading on the s-
meter with a long wire than the wellbrook, especially if your loop is
short, but the quality of the signal on the wellbrook is superior.

One of the oddest DX catches I got with the 20ft loop is
http://www.lazygranch.com/sound/lax_530_etgravel.wav
I was parked on "the gravel"
N37.43225 W115.44496
near Area 51. I did a search for unknown NDBs, which I did find though
they are now turned off. The next search was to see if they had any
TIS. Now TIS is not all that odd at military installations, though I
doubted Groom Lake would have one. Searching the typical TIS
frequencies I picked up the TIS for LAX. That is about 280 miles away.
However, you need to realize how "quiet" Central Nevada is regarding
RF. Even in the middle of MOAs and next to the largest continental
military reservation, there is much less hash than even a mid-size
town puts out.

Wellbrook is pretty mysterious about what they put in their boxes. The
units themselves are potted, though that wouldn't stop anyone serious
about copying their gear.What you need to realize is how little
product they ship. Comparing serial numbers with my ala100 and a
friends, we figured they were shipping about one a month to North
America. In other words, If they had a Wellbrook users convention, I
don't think they would need to book it in Vegas. [There is a wellbrook
loop on the top of the Las Vegas convention center. ]

Anyway, most people think the ALA100 has a transformer on the front
end and a signle ended amp. The ALAM may be all active. I don't know
if that makes a difference in performance, but floating the antenna
seems like a good idea.

Unlike the KIWA, the Wellbrook is wideband. This is good in the sense
that you don't need to tune the antenna and the radio at the same
time, but it does require a decent radio since the antenna is not
doing any filtering.

Wow, that is an amazing clip considering the circumstances. What was

M...Sushi,

Glad that you like the Wellbrook ALA100 Loop Antenna
so much and that it meets your Radio Listening needs.

I would Expect the Wellbrook ALA100 Loop Antenna to out
perform the Palomar MLB-1 with a 100 Foot Antenna.

For $230 more in Cost and at ~ Five Times (5X) the price.

Wellbrook - ALA100/M L/M Aperture Loop Antenna
http://www.wellbrook.uk.com/ALA100Ma.html
North American Version with PSU
http://www.wellbrook.uk.com/buy.html
Price : $258.00 +S&H $30.00

Palomar Engineers - MLB-1 "Magnetic Longwire Balun"
http://www.palomar-engineers.com/MLB-1/mlb-1.html
Price : $50.00 +S&H $8.00

Plus for your Radio Listening interests and needs the
Welbrook is a whole lot more 'portable' then trying to
Erect a 100 Foot Wire Antenna on the Side of the Road.

I bought my Wellbrook before the Bush Crime Family devalued the
dollar. Sure, we pay more money for high quality goods from the UK and
EU, but just think about the bargains we now get for the "cough cough"
made in China imports.

If it wasn't for the weak dollar, gas would cost about 30% less. Every
time those morons at the Fed cut interest rates, gas gets more
expensive.

I didn't log the call. The dates on my server are no longer when I did
the upload, so I would have to do some research to get the date I
recorded it. I think it was at night. Of course, I realized later that
to find a local LF source you should do this in the day. Even so, I
could received NDBs from Canada during daylight hours when out in the
Central Nevada desert.

The setup for that recording:

The black rods are tent poles. The plastic came from Tap Plastics. The
PVC is obvious. The base is an old patio umbrella stand. I have
another one twice as big, which is four time the aperture.

I suppose I should bring the gear out there again and see if I can
repeat the LAX TIS.
