  • Patent number: 9293804
    Abstract: An antenna includes a first radiating array coupled to the mast and a second radiating array coupled to the mast. Each of the first and second radiating arrays comprises a plurality of dipoles associated with a radiation frequency, each dipole coupled to the mast by a standoff. The two arrays are mounted approximately opposite to each other relative to the mast, rather than one array on top of the other array. The antenna may be part of a Positive Train Control (PTC) system and be disposed in proximity to a train track.

  • Patent number: 6160460
    Abstract: In one form of the invention, a resonant cavity filter (50) is disclosed, comprising an input port (210) for receiving an input signal, a dielectric resonator (204) in a cavity, the dielectric resonator operable to receive an input signal from the input port and further operable to produce an output signal at a resonant frequency of the cavity, an output port (212) operable to receive the output signal and a tuning plate (308) disposed in the cavity, the tuning plate coupled to a control means operable to cause movement of the tuning plate, thereby changing dimensions of the cavity, the control means operable to determine a frequency of the input signal, retrieve an expected tuning plate position from a memory (514) based on the frequency, and move the tuning plate to the expected position. Other systems, devices and methods are disclosed.

  • Patent number: 5917455
    Abstract: An antenna assembly having an operating frequency and a vertical radiation pattern with a main lobe axis defining a downtilt angle with respect to the earth's surface. The antenna assembly comprises a plurality of antennas in first, second, and third antenna groups disposed along a backplane, the backplane having a longitudinal axis along which the antennas are disposed, and a phase adjustment mechanism disposed between the second and third antenna groups, such that adjustment of the phase adjustment mechanism results in variation of the vertical radiation pattern downtilt angle.

  • Patent number: 4964065
    Abstract: An electronic communication system monitor in one embodiment has sensors for sensing electrical and environmental conditions for communication system elements. Control relays connect the elements to a programmable controller. The programmable controller has a keyboard, display, printer and modem for remote communication of information; especially alarms providing notice of operating conditions outside acceptable parameters. A second embodiment provides a logic circuit connected to selected sensors which determines when a combination of conditions exist to cause alarm and automatically activates a remedial device to alleviate a potential problem.

  • Patent number: 4823280
    Abstract: An electric power monitor system for radio communication (trunking and paging repeater base station) systems includes a plurality of input switches, power sensors, a power monitor having a display, keyboard, and microprocessor, a printer port, and communications port. The input switches facilitate alarm inputs, for example, unauthorized entry, flooding, fire, and temperature of the antenna site. The power sensors include bidirectional and unidirectional sensors connected to a communication system having tunable components for producing analog signals indicative of system component performance. The power monitor measures, determines, and reports locally and/or remotely the power output and standing wave ratio of transmitters and antennas, insertion loss of combiners and power to and SWR of antennas and alarms.
