Have you used one or both of these loop active antennas?

How do they perform? Are they worth the purchase price?

I just got the Wellbrook ALA100. This is a "roll your own loop" loop
antenna. [You get two binding posts to which you attach your home made
loop.] I find the low frequency (BCB down to beacons) performace to be
better than any long wire. I'm still evaluating if it is better than a
long wire for shortwave performance. It is certainly easier to rotate
a loop to null an interfering signal than it is to rotate a long wire.

Sad to say, I don't like the Kiwa Pocket Loop - everything else they do
is first rate. I think the Q is too low on SW or something, anyway
I can't null anything with it there, and it doesn't seem to pull
anything new in. It's also a kludge to operate. Maybe it's pulling
more electric field signal than magnetic on SW. It's no big deal
on MW either.

The regen box for it is a disaster, at least mine was, very unstable
and impossible to use. It may be that I got a bad one, but it's been
back and forth three or four times, so evidently it meets their
specs from their point of view. I just wrote the thing off and don't
use it any longer.

By comparison their MW loop is excellent, alas no longer made.
Stable, deep nulls, very well behaved regen circuit, sturdy
construction.

Go with a broadband active antenna instead.

I have a couple Wellbrook ALA1530's outdoors that work fine. They
have an indoor version I think. (I could go into a confusing discussion
of the power polarity options and why you want to get the UK version
probably and skip their wall wart, so that you can use negative ground.)
