Hello Adam, Brad & Eric,

Thanks for your replies.

Yep, I had a look at those reviews and can see the very different ratings.

No these are not magnetic loop antennas, Adam.

I have spoken to Rob (VK2VRB). He is already helping Allan (VK2VEC) with 
his setup in the attic. Rob will come over to my place on Wednesday and 
we will discuss possible configurations in the attic. I am interested to 
hear what Rob has to say too. I shall also write an e-mail to David at 
Benelec and ask if he has ever heard of Isotron antennas. I shall let 
you know the outcome of both investigations.

Salut,
  Mathias
