I got to compare the Kiwa, the Quantum Qx and the 1 meter (diameter)
Wellbrook 1530 loop on a Drake R8B. First of all, regarding the Kiwa,
you don't need the regen if you have decent radio. Thus,***the Kiwa
since it only works on BCB. The Wellbrook beat the smaller Quantum Qx,
but I don't know how it would compare to the larger Quantum pro. Then
again, the ALA-100 and your own wire loop is less than the larger
quantum.
Unless your radio sucks, I'd get the Wellbrook and go untuned. The
advantage to the wellbrook is you get full HF coverage, while the
Quantum only goes to 2MHz.
The ALA100 is billed as an outdoor very long wire version of the
Wellbrook loops, but It works well with about a 10ft (length) wire, and
exceptionally well with about 40ft of wire.

The website doesn't explain the product very well. Here is one
implementation:

The amplifier is at the bottom of the loop.

Not shown is the wallwart and the interface box you put near the radio.
I've hunted NDB's with the ALA100 using a loop no bigger than a pie
plate. Of course, this is without 20 miles of the NDB.
