Yes, that's what I was thinking of too.

Spending a little time on Google, it seems that mag loops do work well on the HF bands, but for optimum performance, they need to be tuned and then have very tight bandwidths (a few kHz) so need a remote-controlled tuner (thank goodness I kept my box of stepper motors). There are lots of articles on this subject, many where the loop is being used to transmit and receive, and claims that they will compete against HF dipoles.

It seems that intolerance of large radio aerials in residential areas, in many countries, has been pushing the subject along quietly for some time.
