## Abstract

An antenna supporting base post, in which an antenna element is slidably fitted. The base is itself fitted through a body panel of a motor vehicle, where it is firmly secured in place with appropriate bushing means fitted over the base post and against the top and bottom surfaces of the body panel, by threading a tubular mount onto the top end of the base post. The tubular mount has a flexible body portion which enables the antenna element to tilt, when it is in its extended position, the tilt occurring freely under the impacting force of any external object accidentally hitting against the antenna element during vehicle travel.

## Claims

### Claim 1

A mobile antenna mount comprising a telescoping antenna means, upper and lower hemispherical bushing means having at least a bottom portion for positioning above and below a body panel for supporting said antenna, a bore extending through said bushing means with sufficient angular clearance to enable an adjustment of said antenna position on said panel, flexible coupling means between said antenna and said bushing means to enable a deflection of said antenna responsive to a mechanical force acting upon said antenna, flexible co-axial cable means free of contact pressure directly extending from the bottom of said telescoping antenna means for conveying signals between said antenna and equipment associated therewith, and an elongated encasing means extending downwardly from said lower hemispherical bushing for receiving said telescoping antenna when in a retracted position, said coaxial cable being movable within said encasing means to enable said antenna to telescope between an extended and a retracted position.

### Claim 2 (depends on 1)

The antenna mount of claim 1 further comprises waterproof sealing means interposed between at least one of said bushing means and said body panel.

### Claim 3 (depends on 1)

The antenna mount of claim 1 further comprises storage drum means for taking up or paying out said coaxial cable as said antenna telescopes.

### Claim 4 (depends on 1)

The antenna of claim 1 further comprises power drive means for extending or retracting said telescoping means.

### Claim 5 (depends on 1, 2, 3, 4)

The antenna of any of the claims 1, 2, 3 and 4 further comprises pliable reinforcing means covering said coaxial cable for protecting it while said flexible coupling means is flexing.
