Valid point from Chuck. I've never had an overload problem with any of my
ALA. The FLG 100, yes. It needs the 10 dB attenuation, but the ALA 100
works fine, even with my 10 kW CFAX 1070 within 1 to 2 km from my QTH.
Never any overload. 73, Walt

I'm not convinced that the impedance mismatch would change enough to make a
loop bigger than 20m be less effective than a 25m loop.
I wonder whether Andy factored in overload and was saying "bigger might cause
urban overload problems".
But this is speculation as Wellbrook doesn't really
I'm a fan of the Wellbrook for sure but I use much larger loops - one
is around 80m in circumference. The top is around 120'. It was made this
dimension because a: that's what I first tried and b: it's just able to
handle the medium wave energy present. It's oriented to null the Edmonton
Wellbrook's documentation for the ALA100LN says "The antenna uses a 20m
circumference thin wire loop to provide optimum s/n. " Apparently, larger
loops provide more of a mismatch to the input impedance of the amplifier,
so one doesn't get the expected additional gain from a still larger loop.
That's the other wonderful thing about the ALA 100. Any old tree, any
shape, virtually works just fine. Mine have been square, round,
triangular, and anything between, and they've always worked well. Very
forgiving!Walt

I was building a 27’ long bamboo radio tower today and threw up a 30’ (17’
diagonal ALA100) to test out a spot in my front yard which is, ironically,
quieter than my backyard.
The WELLBROOKS are a joy to use in that you can throw a tangle of wire at a
tree and have an instant antenna.
It's interesting, but I haven't yet found a, "too big circumference" with
the ALA. It seems to be an extremely robust piece of equipment which
allows virtually any size to work. The biggest I've used was about 50' x
20', and also 2 loops of 30' x 20'. Not sure what happens if it is too
large
Andy Ikin would’ve told you that a standard ALA100 is probably at its best at a
loop of wire 20-30 feet long.
Bigger is not always better with these units.

I could’ve made it even larger but I wanted a cross between large size and
manageable I could’ve done 40-50 feet long. Who knows what I’ll decide
to do when I end up somewhere else

Excellent dimensions, Paul. The larger the loop, the more gain you will
have. Mine are always as large as I can make it! Walt

When I land somewhere again where I have a bit of yard space (i dont have

Correction: The Wellbrook ALA series is optimized for 100khz to 30 MHz not
really 10 KHz - although you will hear lots of stuff < 100 KHz on it.

I liked the highly portable Doxytronics loop for that reason too. I once
took it with me on a hike along with a portable receiver for some "on the
trail" SWLing. It only takes a minute to assemble or disassemble the PVC
frame and coax loop element.
I'd forgotten about Doxy's web site; in fact,
I remember when the Toyota dealer next to the 22 freeway used to have a low
power station. ms

I have 3 Wellbrook ALA100's and two FLG100's (for the KAZ, FLAG, Pennant
antennas...)
They have defined and shaped my listening over the years - love them /
could not live without them.
Balanced and quiet performance from 10 khz to 30 Mhz.
Highest vote for these products.

FWIW,
I have been using a Wellbrook ALA 1530ln feeding into a Quantum Phaser for
several years. The Quantum Phaser amp quiet and provides a nice signal boost in
addition to the Wellbrook amp that came with the ALA 1530ln. The Wellbrook loop
is located indoors in my shack.
Thanks a lot Guy.
My primary interest for the loop will be MW, so the Doxy wouldn’t be a good
fit.
My G5RV Is fine for the rather casual SW/amateur listening I tend to do.
Appreciate the info and video link!

Thank you Steve. That’s good to know. I have played around with LF from
time to time.
My MFJ experience over the years has been a bit mixed.

In addition to the loops already mentioned, there's the MFJ 1888
broadband amplified loop. I bought one some time back mainly just to see
how well it worked at LF, which is my primary use for receive-only
amplified loops. The MFJ loop does not work at LF despite the
typographical claim in the
Guy, you can also buy it online on their website http://doxytronics.com/
Doxy is portable.. its collapsable, you could easily stuff it in a backup

Hi Russ,
I've owned the DoxyTronics loop that Paul mentioned, and also have compared
it to my Wellbrook ALA1530LN Pro.
The DoxyTronics is no longer sold under that name, but it still comes from
an Ebay seller in Oregon who goes by the username "antennas4less". In his
auctions he calls it a

Thank you Paul for your observations.
I’m primarily interested in MW. How did it do therebased on your 3–15

Good Morning,
I will likely be purchasing a magnetic loop this fall. I wasn’t able to find

Ability to withstand the weather is of prime importance. While cost is always
