Receive loop antenna; these work amazingly.
Built and tested.
A must for all stations, allowing you to hear those weak stations with less noise.
These are passive antennas and do not require a power source.
Most modern radios have a dedicated receive antenna connection; an antenna selection switch can be used if your radio does not.
Do not transmit into these antennas; receive only.
