Top Mount Mast Antenna Reinforcement

摘要

A mounting apparatus for a top mount mast antenna includes a secondary mounting bracket positioned below the fender panel to stabilize the antenna attachment screws extending through the antenna base into the fender panel of the automotive vehicle on which the antenna is mounted. The secondary mounting bracket is formed with a generally circular reinforcement collar that projects upwardly through the opening in the fender panel. The reinforcement collar has opposing retention tabs that pass through recesses formed in the opening. A rotation of the secondary mounting bracket within the opening rotates the retention tabs to a position overlying the fender panel, and moves deformable bosses into alignment with the screw holes in the fender panel. The rotation of the secondary mounting bracket is halted by the engagement of a closed side of the bosses with a flange of material created by the piercing of the screw holes.
