Abstract: This invention is a bracket for supporting a truck cab radio antenna. Its main characteristic is its simple, rapid, and easy attachability and detachability to and from the outside rear-view mirror bracket. It consists of a tube of about the same height as a standard truck rear-view mirror bracket. A short rod is inserted and rigidly held within the top of the tube. A similar but somewhat longer rod is inserted into the bottom of the tube, wherein it is free to slide. Attached to the top insert is a top plate extending on both sides of the tube. At one end, this plate is provided with a central hole for the attachment of the antenna; while rigidly attached to the other end of this plate is a semicircular holder which fits over the top of the mirror bracket. A plate and similar holder is attached to the bottom of the sliding rod to fit under the bottom of the mirror bracket. A spring contained in the tube joins both inserts, and holds tightly the antenna bracket to the rear-view mirror bracket.
