Abstract: A switch provides a sprinkler valve signal to a first sprinkler valve, and after a period of time, diverts the sprinkler valve signal to a second sprinkler valve. The switch is serially wired into sprinkler wires running between a timer and at least two sprinkler valves, and operates off the sprinkler valve signal present in the sprinkler wires. When the sprinkler valve signal comes on, the switch provides the sprinkler valve signal to the first sprinkler valve and starts a clock which counts for a period of time T. When the period of time T passes, the clock switches a relay which switches the sprinkler valve signal to the second sprinkler valve.

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.
