FIELD: multifrequency antennas for motor vehicles. SUBSTANCE: multifrequency antenna 112 and connector 10 are installed in low-noise communication channel between multifrequency radiophone or between many single-frequency telephone sets each operating at different frequency in motor vehicle 16 and surrounding atmosphere of motor vehicle. Connector 10 has inner and outer members 32 and 22, respectively, disposed in opposition with motor vehicle window in-between. Each member 22 and 32 is conical in shape and is disposed in immediate proximity of other member so that wider end of one member occurs in opposition to narrower end of other member. Multifrequency radiator 112 is attached to outer member 22. Radiator has several relatively isolated radiating elements 114, 116 secured to common base 118; each radiator is specifically shaped to radiate respective frequency. EFFECT: provision for developing multiple-band radiator for motor vehicles. 16 cl, 37 dwg
