Abstract: A known mounting for attaching an antenna pole to a motor vehicle window comprises an antenna mounting plate which is fitted to the outside of the window glass and an inner plate which is fitted to the inside of the window glass. The inner plate includes an antenna connector and a connector for connecting a coaxial cable to a receiver/transmitter. With the intention of simplifying the antenna mounting in a manner which will enable the antenna pole to be readily removed but nevertheless to be securely held when the vehicle is in use, and also with intention of eliminating the deleterious effect of atmospheric conditions on the mounting and the component parts thereof, so as to prevent corrosion or rusting, the mounting plate is made of an electrically non-conductive material and has formed integrally therewith an attachment which coacts slidable with an antenna-carrying attachment piece.
