MW antennas that are NOT loops

While loops are certainly a popular weapon of choice for DXing on MW, there are other antenna designs that can do the job; namely ferrite rod and ferrite sleeve antennas.

Before you go diving into the IRCA and NRC reprints (the links are in the wiki below), you can read a few articles on the subject via the popular SWLing.com website

Technically a ferrite rod and ferrite sleeve antennas are loop antennas often even often called ferrite loop antennas, just not open air ones. Using ferrite instead of open air inside the turns allows fewer turns and size. I have built some of these myself. (A former note to myself, when using SuperGlue to fix the wire turns in place, be certain to not hold those while winding more turns or you will glue yourself to the antenna.)

Hmmm...I never thought of this. And yes, best not to get too sloppy with the Super Glue (heh)

Worst part as the ferrite rods had grooves that the glue moved in without me seeing. Twice I found myself glued well to the antenna I was winding.

There was a period a while back when I was getting my hands on every old desktop AM radio I could find at flea markets Etc, just so I could harvest the ferrite rods and variations, I liked the ones where the loop was fixed to the rear panel of the radio.
