1. A cell antenna system comprising:
- at least one cell antenna; and
cell antenna mounting apparatus for mounting the cell antenna to a structure, the mounting apparatus providing remote tilt adjustment for the cell antenna and remote heading adjustment for the cell antenna, the mounting apparatus including;
a vertically mounted linear actuator; and
linkage connecting the linear actuator to the at least one cell antenna to couple a vertical motion of the linear actuator into a tilt adjustment of the at least one cell antenna.

Abstract
A mounting apparatus for remotely adjusting the tilt and heading of cell antennas. Antenna tilt is provided by the cooperation of a hinged lower tilt bracket and an upper tilt bracket connected to the antenna by links. The upper tilt bracket is mounted to a vertically translating dust cover. Vertical motion of the dust cover is translated to tilting motion of the antenna by the links. Heading adjustment may be provided uniformly to entire sectors of antennas using a Pitman arm arrangement, or may be provided to each cell antenna individually using a helix heading adjustment apparatus.

19. A cell antenna system comprising:
-
A plurality of cell antennas; cell antenna mounting brackets for mounting the cell antennas to a structure, the mounting brackets providing individual antenna tilt adjustment for each cell antenna, and individual heading adjustment for each cell antenna; tilt actuators for adjusting the tilt of each of the cell antennas; and helix heading adjustment apparatus for adjusting the heading of at least one of the cell antennas, the helix heading adjustment apparatus comprising; a linear actuator; a helix piston vertically translatable by the linear actuator and having helical slots; and follower bolts adapted to ride in the helical slots, thereby translating a linear motion of the helix piston into a rotational motion of each cell antenna.

20. A cell antenna system comprising:
-
at least two cell antennas; at least one cell sector including at least one of the antennas; and remote helix heading adjustment apparatus for adjusting the heading of at least one of the at least two antennas, wherein the remote helix heading adjustment apparatus comprises; a linear actuator; a helix piston vertically translatable by the linear actuator and having helical slots; and follower bolts adapted to ride in the helical slots, thereby translating a linear motion of the helix piston into a rotational motion of the one of the at least two cell antennas, wherein spring loaded guides reside on interior ends of the follower bolts and cooperate with the helical slots.
