摘要:
In a high frequency radiation cable, with groups of openings arranged periodically in the outside conductor of a coaxial cable, the number of openings per periodic length increases in sections along the cable, where the sections are whole number multiples of the periodic length.
摘要:
In a radiating high-frequency coaxial cable with openings in the outside conductor (6), which are essentially slots (7) cut perpendicular to the cable axis, sections with periodically repeating slot configurations are provided along the cable, which differ in period length with a constant number of slots per period length, and/or differ in the number of slots per period length while the period length remains constant.

Systems and methods for field data gathering and which provide flexible configuration options for a central office. The system, run from, mobile computing devices, provides a free-flowing data gathering experience while only requiring what the central office needs from the field. The central office can configure the system to accept different types of data by way of different data input means available to the mobile computing device. Only the data needed by the central office need be collected by the mobile device operator. The data format is defined by the central office and is uploaded to each of the relevant mobile computing devices for use by the operators. Once each data set has been collected by an operator, the data package with the data set is scheduled for transmission to the central office once a connection with the central office can be made.
摘要:
A radiating coaxial high-frequency cable is provided with openings in the outer conductor which are in the form of slots (5) arranged substantially perpendicular to the cable axis. The slots (5) are arranged in sections which are arranged consecutively without gaps in the longitudinal direction of the cable and whose axial length is dimensioned according to the high-frequency energy to be transmitted. The number of slots (5) is greater in the sections which are farther away from the feed location of the high-frequency energy than in the sections which are closer to the feed location. When the length of the cable is increased, several sections (A) with an identical number of slots are arranged consecutively without gaps, provided that subsequent sections (A) have a larger effectual opening when the system damping between the high-frequency cable and an antenna located outside the cable reaches a predetermined value.

A coaxial connector (1) is adapted for use with a coaxial high frequency cable having an external conductor which concentrically surrounds and is spaced from a tube-shaped internal conductor with at least one optical wave guiding element therein. The coaxial connector has an internal contact part (5), which can be electrically connected with the internal conductor of the high frequency cable, and is positioned concentric with a longitudinal axis of the connector. A plug-in element (15), which is electrically connected to the internal contact part (5), is angled with respect to the longitudinal axis of the connector. The plug-in element (15) is surrounded by a ferrule terminal (21), with a space between them, which can be electrically connected to the external conductor of the high frequency cable. The at least one optical wave guiding element, which is located inside the tube-shaped internal conductor of the high frequency cable, can exit in a simple manner from the coaxial connector (1) through a concentric passage hole (9) in the internal contact part (5).
