Abstract: An antenna mount to be received within the trunk of an automobile, truck or other vehicle, comprising a bracket member adapted to be secured to the trunk rain channel and incorporating a generally vertically disposed mounting flange, a mounting member adapted to extend outside of the trunk and having a support section to be secured to the mounting flange of the bracket, aligned rib and groove elements on the respective bracket and mounting members, and a wing nut - bolt assembly adapted to releasably secure the mounting and bracket members to one another with the respective rib and groove elements in engagement so as to prevent relative movement therebetween and maintain the integrity of the composite mount. When it is desired to remove the antenna from the vehicle loosening of the wing nut facilitates disassembly of the mount and stowage of the antenna within the trunk, thereby minimizing the risk of theft.

Abstract: In an antenna window mount assembly of the type including a bracing member securable within the frame of a window, and a supporting member securable in outwardly extending relation from the window, an improved T-shaped swivel joint releasably secures the supporting member to the bracing member to permit the supporting member to be moved between the outwardly extended position and a swivel position in which the free end of the supporting member is near the window.

Abstract: An antenna mounting assembly mountable exteriorly of a window and adapted for use with a vertical CB antenna comprises a bracing member adapted to be secured within the frame of the window; a plurality of horizontal angularly oriented ground plane elements; a boom assembly including a supporting member having a mount section, means for securing the supporting member to the bracing member for orienting the supporting member outwardly from the window and means for swivellingly securing the ground plane elements in a radial arrangement to the mount section, the swivelling of the elements defining a horizontal plane; and means for removably securing the vertical CB antenna to the boom assembly substantially at the center of the radially arranged ground plane elements, the securing means orienting the antenna generally perpendicular to the defined plane whereby the swivelling movement of the ground plane elements in the defined plane is used to increase the directional strength of the signal transmitted from the a
