Abstract
Abstract A radio tuner is detachably coupled with a cassette tape recorder having a rectangular form. It includes an L-shaped tuner casing which is adapted to mate with two adjacent, mutually perpendicular sides of the tape recorder. A rod antenna is received within a casing portion which extends along the longer side of the recorder while a ferrite bar antenna is received within another casing portion which extends along the shorter side of the recorder.
