FIELD: connection of portable radiophone to peripheral radio- frequency test equipment. SUBSTANCE: preferable alternative of connecting device 404 has first connecting assembly 406 inserted directly in antenna input of radiophone to function as normal antenna substitute. Matching electrical components 410 on wiring board 400 are used for matching antenna input impedance of portable radiophone. Second connecting assembly 408 is commonly used for standard radio-frequency connectors to connect radiophone antenna input to peripheral equipment. EFFECT: reduced size of antenna adapter. 17 cl, 7 dwg
