"Ferroceptor"[8] is an older alternative name for a ferrite rod aerial, particularly used by Philips where the ferrite core would be called a "Ferroxcube" rod (a brand name acquired by Yageo from Philips in the year 2000). The short terms ferrite rod or ‘loop-stick’ sometimes refers to the coil-plus-ferrite combination that takes the place of both an external antenna and the radio’s first tuned circuit, or just the ferrite core itself (the cylindrical rod or flat ferrite slab).
