Thanks for that link.
I don't understand how it is a magnetic aerial although he uses the term. To me it has to be an aerial shielded from the E part of the received signal. So shouldn't it be a wire inside a tubes as per the Wellbrook? Wonder how they get the ferrite inside the tube and what difference that makes.
In the Den I have a large window and I could put a tube all the way around it with an inner wire, coupled to the amplifier. Any ideas if that would work? I understand that shape is not critical, it doesn't have to be round and larger presumably means more signal? With the Wellbrook, for the lounge best radio, it is on a rotator bought NOS for a very low price but for MW and LW I don't find it any advantage so having a window aerial fixed in a single plain wouldn't matter. Actually the Wellbrook started off on the window sill of the Den and worked very well for the radios in there, with large signals. This was also the case when tried with the HMV 650 just loose in the lounge. LW R4 closed the eye tube with considerable overlap but now garden mounted and 60 feet away signal is down and eye not fully closed. That just must be the loss in the RG59 coax.
thanks for ideas Gary
