I have been delving into RF and trying to get into ham radio. I have been researching loop antennas, and while learning what makes loop stick antennas work, I encountered a schematic similar to the following, where there are four separate loop stick antennas each surrounding a common ferrite core. I cannot find any information on exactly what type of antenna this is, or what it would be used for (radiation pattern etc.).

I am an ME, and am relatively new to RF and antennas, but have always had a keen interest in it and I am willing to learn. Any input would be most appreciated.

I have seen many antennas and that is a new one for me.
Please give a web link, a photo, or a reference, so we can get more information.

Depending on the way it is oriented and connected, it would seem that it will be sensitive to different polarisations, or maybe it was designed to reject jamming from a particular direction.

Good for you.

It looks like each half-coil will cancel the other. Can you post a link to the actual schematic?
