Abstract

An antenna mounting for mobile and portable radios with an antenna element which can be quickly and easily removed, replaced, or secured in selectable positions manually without hand tools. The antenna is received and supported by a manually rotatable setscrew which engages a complementary threaded opening in a selectively positionable arm assembly. The arm assembly is pivotally attached to a fixed vertical support perpendicular to the antenna mounting base. The pivoted arm allows the antenna setscrew'"'"'s bottom tip to be selectively positioned and secured relative to indentations along the arcuate surface of a semicircular shaped structure on the vertical support. The antenna may be physically removed for safekeeping by reversing the aforementioned procedure.

Claims

1. A selectively positionable antenna mount comprising

a base plate adapted to be secured to a mounting surface,

a generally semi-circular support element having a flat edge and a curved edge defining an arcuate surface, with said flat edge generally parallel to said base plate and said arcuate surface extending perpendicular therefrom, said support element having a center point generally equidistant from all points on said arcuate surface, and said arcuate surface carrying a plurality of indentations disposed radially from its center point,

an arm pivotally attached to said support element at the center point of the arcuate surface, said arm being selectively positionable in a plurality of desired angular locations along the arcuate surface,

a manually removable antenna element with bottom tip received by said arm and being positionable therewith, and

clamping means carried by said arm for mechanically engaging and securing said arm and antenna element to said support element in a desired angular position relative to the base plate, said means including a manually actuable setscrew receiving said antenna element, said setscrew being received in a threaded hole in said arm with said setscrew having a tip which is selectively engageable with at least one of said indentations to secure said arm in a desired angular position relative to said base plate.

2. The structure of claim 1 in which said setscrew has an annular shoulder spaced from said arm to define an annular channel when said setscrew is fully engaged with a selected indentation, and having resilient tensioning means in said annular channel for preventing unintended untightening of said setscrew.

3. The structure of claim 2 in which said resilient tensioning means is an elastomeric O-ring.

4. A selectively positionable antenna mount comprising

a base plate adapted to be secured to a mounting surface,

a generally semi-circular support element having a flat edge and a curved edge defining an arcuate surface, with its flat edge generally parallel to said base plate and its arcuate surface extending perpendicular thereto,

the curved edge of said support element defining an arcuate surface having a plurality of indentations disposed radially from the center point of the arcuate surface,

pivot means at the center point of said support element,

a clevis rotatably supported on said support element by said pivot means, said clevis being selectively positionable in a plurality of angular locations along said arcuate surface and having a threaded through-hole which is radially alignable with a selected one of said indentations,

a manually operable setscrew received in said clevis threaded through-hole, and having a tip which is selectively engageable with one of said indentations to secure the clevis in a desired angular position relative to the base plate, and

an antenna element secured to the setscrew and being positionable therewith.
