Antenna mount
A mount for an antenna includes: first and second generally C-shaped arms, each with upper and lower free ends; equipment face mounting brackets mounted on the first and second arms; and lower and upper plates mounted to a post. The upper free ends of the first and second arms are pivotally mounted to the upper plate, and the lower free ends of the first and second arms are pivotally mounted to the lower plate, such that the first and second arms are movable between retracted and extended positions. The first and second arms are fixed in the extended position relative to the upper and lower plate via fasteners inserted through holes in the upper and lower free ends of the arms and in the upper plate, the pivotal mounts and the holes defining a desired angle between the first and second arms in the extended position.

wherein at least one of the upper and lower free ends of the first and second arms has a flattened section with raised edges sandwiching a recess, and wherein the fasteners are threaded fasteners having a head that is prevented from rotating when inserted into the recess between the raised edges.
2. The mount defined in claim 1 , wherein the fasteners are threaded fasteners, and wherein the pivotal mounting of the first and second arms is achieved with threaded fasteners.
3. The mount defined in claim 1 , wherein the equipment face mounting brackets are substantially coplanar when the first and second arms are in the extended positions.
4. The mount defined in claim 1 , wherein the upper plate is an upper azimuth plate having an arcuate slot, and wherein a bracket is attached to the post, the bracket having an adjustment member received in the slot so that the mount can rotated about an axis defined by the post.
5. A mount for an antenna, comprising:
first and second generally C-shaped arms, each with upper and lower free ends;
equipment face mounting brackets mounted on the first and second arms;
lower and upper plates mounted to a post;
wherein the upper free ends of the first and second arms are mounted to the upper plate, and wherein the lower free ends of the first and second arms are mounted to the lower plate; and
wherein the first and second arms are fixed in an extended position relative to the upper plate via fasteners inserted through holes in the upper, free ends of the arms and in the upper late, and the first and second arms are fixed in the extended position relative to the lower plate via fasteners inserted through holes in the lower free ends of the arms and in the lower plate;
wherein the mounts between the upper free ends of the first and second arms and the upper plate and the mounts between the lower free ends of the first and second arms and the lower plate are pivotal mounts, such that, absent the fasteners the first and second arms are movable between the extended position and a retracted position, the pivotal mounts and the holes defining a desired angle between the first and second arms in the extended position
further comprising a tilt angle selection mechanism, comprising:
a lower bracket attached to the post of the antenna mount, the lower bracket including lower side panels;
an upper bracket attached to the post of the antenna mount, the upper bracket including upper side panels, each of the upper side panels including a plurality of holes;
upper and lower bases for mounting the antenna mount to an antenna tower;
wherein the lower side panels are attached to the lower base at a pivotable joint; and
wherein the upper side panels are attached to the upper base via the insertion of a member through a selected one of the plurality of holes and into the upper base, the insertion of the member preventing pivotal movement of the lower bracket relative to the lower base.
6. The mount defined in claim 5 , wherein the plurality of holes is regularly spaced.
7. The mount defined in claim 5 , wherein the upper and lower brackets are attached to the post via U-bolts.
8. The mount defined in claim 1 , wherein the upper and lower plates are upper and lower azimuth plates, each having an arcuate slot;
wherein the arms attached to the upper and lower azimuth plates;
wherein the arcuate slots are configured with a radius of curvature that is substantially collinear with an axis defined by the post; and
further comprising upper and lower brackets attached to the post, each of the brackets having an adjustment member received in the slot of, respectively, the upper and lower azimuth plates so that the frame ran rotated about the axis defined by the post.
9. The mount defined in claim 8 , wherein the adjustment members comprise threaded fasteners that can fax the upper and lower azimuth plates relative to the upper and lower brackets.
10. A mount for an antenna, comprising:
first and second generally C-shaped arms, each with upper and lower free ends;
equipment face mounting brackets mounted on the first and second arms;
lower and upper plates mounted to a post;
wherein the upper free ends of the first and second arms are mounted to the upper plate, and wherein the lower free ends of the first and second arms are mounted to the lower plate; and
a tilt angle selection mechanism, comprising:
a lower bracket attached to the post of the antenna mount, the lower bracket including lower side panels;
an upper bracket attached to the post of the antenna mount, the upper bracket including upper side panels, each of the upper side panels including a plurality of holes;
upper and lower bases for mounting the antenna mount to an antenna tower;
wherein the lower side panels are attached to the lower base at a pivotable joint; and
wherein the upper side panels are attached to the upper base via the insertion of a member through a selected one of the plurality of holes and into the upper base, the insertion of the member preventing pivotal movement of the lower bracket relative to the lower base.
