rf-systems WFL antenna?
 

Hello,
can you explain this antenna mentioned on this site?

A almost flat swr response with such a small antenna must be a folded T2FD
antenna.
Is there someone who has tested this antenna?

It sounds like someone is trying to sell junk at a high price. Unless the
price is also for the supporting poles. Oxygen-free copper wire sounds like
the HI-FI boys and their Monster Wire are at it again.

Hi Johan, I think you have the right idea. A broadband power
limited small antenna suggests resistive loading at the feedpoint. It
will work, just not very well until you get above the frequency at
which the wire portion starts having some efficiency. As a guess, this
one might do OK above 14 MHZ.
A magnetic loop generally refers to a small loop with a very narrow
bandwith, tuned by a variable capacitor. The claim that this is a
magnetic loop on low bands does not hold up because of the broad band
claim.

Especially since oxygen free is another term for pure copper.

Let's hope someone dismantles one to see what is inside....
