FIELD: present-day mobile radio communication. SUBSTANCE: ecologically safe conditions for use of mobile radio communication are created by tenfold increase of distance from antenna of subscriber's terminal to rear lower part of man's head most sensitive to action of electromagnetic radiation as compared with conventional location of antenna. Under other equal conditions action power of electromagnetic radiation on specified region of head lessens by more than 100 times. Transceiver antenna in this case is located under microphone of subscriber's terminal in butt of its case. Apart from this antenna can be fitted with articulated joint with case to change its spatial position through 180 deg or can be rigidly fixed on hinged microphone part. EFFECT: enhanced ecological safety of radio telephone. 1 cl, 6 dwg, 1 tbl
