Abstract
Abstract A mobile two-way communication antenna is mounted on a metal plate which is pivotally secured to a housing so as to pivot about a horizontal axis. An electric reversible motor drives an elongated screw which in turn moves a cam surface linearly. The cam surface coacts with the metal mounting plate for moving the plate and the antenna between a horizontal and a vertical position. Horizontally extending ground plane elements are provided in applications where the housing is nonconducting. These elements contact the metal mounting plate when the plate is in its full upright horizontal position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
An antenna raising and lowering device comprising: a housing; a substantially planar antenna mounting plate means pivotally secured to said housing and being adapted to be pivotted about a substantially horizontal axis between an inoperative position wherein said plate means is substantially vertically disposed within said housing and an operative position wherein said plate means is substantially horizontally disposed and further being adapted to support an antenna thereon; a cam surface within said housing, said cam surface being adapted to engage part of said plate means for moving the same between said operative and said inoperative positions; elongated screw means and motor means for rotating said screw means for moving said cam surface.
Claim 2
Dependent Claim
113 words
An antenna raising and lowering device comprising: a housing; a substantially planar antenna mounting plate means pivotally secured to said housing and being adapted to be pivotted about a substantially horizontal axis between an inoperative position wherein said plate means is substantially vertically disposed within said housing and an operative position wherein said plate means is substantially horizontally disposed and further being adapted to support an antenna thereon; a cam surface within said housing, said cam surface being adapted to engage part of said plate means for moving the same between said operative and said inoperative positions; elongated screw means and motor means for rotating said screw means for moving said cam surface.
Claim 3
Dependent Claim
16 words
The device as claimed in claim 1 wherein said cam surface is adapted to move linearly.
Claim 4
Dependent Claim
15 words
The device as claimed in claim 1 wherein said motor means includes an electric motor.
Claim 5
Dependent Claim
28 words
The device as claimed in claim 1 further including a block having a threaded bore therein and being threaded onto said screw, said block carrying said cam surface.
Claim 6
Dependent Claim
26 words
The device as claimed in claim 4 wherein said plate means includes a tab means extending therefrom, said cam surface being adapted to engage said tab.
Claim 7
Dependent Claim
16 words
The device as claimed in claim 4 including means for preventing rotational movement of said block.
Claim 8
Dependent Claim
18 words
The device as claimed in claim 1 wherein said housing includes a cover member including an opening therein.
Claim 9
Dependent Claim
19 words
The device as claimed in claim 7 wherein said plate means underlies said opening when in said operative position.
Claim 10
Dependent Claim
40 words
The device as claimed in claim 8 including a plurality of elongated ground plane elements mounted on said housing and extending outwardly therefrom, said plate means being in electrical contact with said ground plane elements when in said operative position.
