Default Kiwa MW Air-Core Loop Antenna {In-the-News} FS / FA

They commonly sold used at the flea market for $250 to $300. I believe
$400 was the new price.

I've had the opportunity to try out the Quantum, Kiwa, and Wellbrook at
the same time. If space is an issue, get the Quantum. If you have a bit
of room, get the Wellbrook. You need a version with a 3ft (meter) loop
to get decent AM BCB. The kiwa is OK, but not as good as the Quantum in
my listening session. Both the Kiwa and the Quantum can be tilted as
well as rotated. I didn't find that useful, but maybe there are time
when that would come in handy. A wellbrook isn't easy to tilt.

The Wellbrook ALA-100 really works well if you set up a large loop. I'm
using 4 turns about 6ft on the side, which really eats up a corner of a
room. [It's an experimental antenna of sorts, and I'll probably settle
for a double loop for indoor use, and use the larger loop when
camping.] Some of the local AM BCB stations are so strong that my 7030
has to cut in the attenuator. Many are so strong that the preamp
doesn't turn on. Note that you need some spacing between the loops to
get any decent HF performance. About 8 inches does the job.

The regenerative controls on the Kiwa are quite useless if you have
decent filters in your radio. Given the limited bandwidth of the Kiwa,
I can't see why you wouldn't choose the Quantum instead. The Wellbrook,
not using a core but rather depending on aperture, works well above HF,
certainly up to 50Mhz. I've used it as low as 24Khz, which has a Navy
FSK signal.

Lastly, the Wellbrook doesn't need to be tuned.

and now you know ~ RHF


All I know is $600 bucks is a lot for a loop antenna. Nice unit
though. What have these Kiwa loops sold for in the past?
