The space between the hood and the 1. In an automobile, acowl having an inwardly offset flange 3 of the cowl is usually filled, at offset flange at its forward edge, a hood having a spaced points by means of pieces of felt or other portion overlapping said flange, a radio antenna,

Radio antenna apparatus for mounting on 8 and 9 respectively, which are parallel with the the outside of a vehicle body having a movable plates 6 and l. The portions 8 and 9 are recover portion, in a manner such that the normally visible portions of the vehicle body are not defaced, said antenna apparatus including a body portion having a mounting extension extending laterally therefrom, said antenna body portion having a cavity extending in and elongated in a direction substantially at right angles to the extending direction of said mounting extension, an aerial having a portion extending into said cavity, and insulating means in said cavity supporting said aerial in said cavity in a generally vertical direction and insulating said aerial from the antenna body portion, with a portion of said mounting extension adapted to be secured to the ve-" hicle body so that said mounting extension portion is substantially concealed by said movable cover portion of the vehicle and being so thin as not to interfere with a normal position of the movable cover portion, with the antenna body portion being exposed on the outside of the vehicle.

3. The combination of a radio antenna, and means for supporting said antenna, said means comprising a pair of brackets, a flat face forming part of each bracket to enable said brackets to be positioned face to face adjacent each other, an

block interconnecting said brackets and interposed between said antenna and said brackets to insulate the antenna from the brackets and means to hold said brackets, said insulator and said antenna in operative relation to each other.

5. In an automobile, a cowl, a hood having a portion overlapping a part of said cowl, a radio antenna, and means for supporting said antenna on said covered part of said cowl, said means comprising a pair of brackets, a flat face forming part of each bracket to enable said brackets to be positioned face to face adjacent each other,

' an insulating block interconnecting said brackets and interposed between said antenna and said brackets to insulate the antenna from the brackets and means to hold said brackets, said insulator and said antenna in operative relation to each other.

6. Radio antenna apparatus for ready mounting on the outside of an automobile in a manner to provide the advantages of an outside mounted antenna and yet without defacing normally visible portions of the automobile body, said antenna apparatus including a metal body portion having an axial bore therein, insulating means providing an insulating lining for said bore, portions of said insulating means extending out of each end of said bore, an aerial supported by said insulating means and extending axially above one of said insulating means portions, an extension of said metal body portion intermediate said insulating means portions and extending to one side thereof and an apertured mounting member connected to said extension.
