Abstract
An adapter (13) for enabling an external antenna, e.g. an antenna fitted to a vehicle, to be connected in place of an existing antenna (7) on a radio, particularly a portable radio telephone (1). The adapter is slidably located in a passageway (6) which may be part of an integral moulding of a radio casing (2). The existing antenna (7) may be slidably located in the passageway such that it can be displaced and so disconnected from the radio when the adapter is fitted. Alteratively, the radio has an internal existing antenna which is switched out when the adapter makes an external antenna connection, e.g., by means of contacts (15,16) mounted in the adapter and in the passageway (FIGS. 3 and 4). The slidable antenna (7) may be in the form of a tape having a bowed cross-section.
