Patent ID: 7417595

Claim:
A mount assembly for mounting a radio antenna in an upright orientation on a curved section of a vehicle, the mount assembly comprising: a top collar disposable during use of the mount assembly on a curved upper surface of a curved section of a vehicle and a bottom collar disposable during use of the mount assembly on a curved under surface of the curved section of a vehicle such that the top and bottom collars sandwich the vehicle curved section therebetween; the top collar having a flat upper surface, a curved lower surface shaped to match and engage with the curved upper surface of the vehicle curved section, and a through-hole extending therethrough from the upper surface to the lower surface; the bottom collar having a curved upper surface shaped to match and engage with the curved under surface of the vehicle curved section, a lower surface, and a through-hole extending therethrough from the upper surface to the lower surface; an electrically conductive tubular connector insertable completely through the through-holes in the top and bottom collars and through an opening in the vehicle curved section, the tubular connector having an external threaded section at least in the regions where the tubular connector extends beyond the upper surface of the top collar and beyond the lower surface of the bottom collar, an electrically insulative sleeve extending axially in the tubular connector, and a center conductor extending axially in the sleeve and electrically insulated from the tubular connector by the sleeve; a mounting ring having an internal threaded section threadedly engageable with the external threaded section of the tubular connector that extends beyond the upper surface of the top collar so that the mounting ring abuts on the flat upper surface of the top collar, and an external threaded section for threaded engagement with an internal threaded section of a radio antenna; and a fastening member having an internal threaded section threadedly engageable with the external threaded section of the tubular connector that extends beyond the lower surface of the bottom collar, the fastening member coacting with the mounting ring to securely hold together the top collar, the fender and the bottom collar so that the flat upper surface of the top collar has a horizontal orientation and the radio antenna has an upright orientation.
