I have used a Wellbrook for many years on 136 and (now) on 472kHz. It
performs well but it will put massive signals from broadcast stations into
your RX! You may need a band-pass filter between the loop and the receiver.
Obviously it is directional.
It will be around 10dB down on a proper aerial, but that's not a problem on
LF.
