There's nothing new about loop antennas, as they dominated receivers for ~50 years until the 1960s transistor radio. Antennas for. MW reception. If you are experiencing bad MW reception then good news would be if the receiver has an external antenna connection point. It should also have a ground (GND) connection as it is rare such a point does not accompany an external antenna connection. Before we start with the discussion of.
