Abstract

Abstract A portable radio, eg a radio telephone, includes a slim, flexible antenna (2) retractable within a compartment (1a) of the radio housing (1). A flexible insulating sleeve (9) is provided in the compartment (1a) around the antenna (2) such that the antenna is able to slide relatively freely therein when the antenna is moved between the extended and retracted position. The sleeve (9) prevents the flexible antenna (2) from rattling against the internal parts of the housing (1) and helps to provide a more positive feel when the antenna is extended or retracted.
