Definitions

  • the invention relates to an antenna socket, in particular for attachment to building walls, with a first coaxial socket for taking TV signals, with a bandstop filter for radio broadcast signals, the output of which is connected to the first coaxial socket, with a second Coaxial socket for taking radio broadcast signals, with a bandpass filter for radio signals, the output of which is connected to the second coaxial socket, with a first connection for a coaxial cable for antenna signal supply, with a second connection for a coaxial cable for antenna signal transmission and with a directional coupler in the form of a line coupler or a transformer coupler, the through-line input of which is connected to the first connection.
  • antenna socket is from DE-A-27 33 200, from DE-C-27 33 220 and from the Siemens brochure "New antenna sockets - the sum of your and our experience", order no. N285 / 5072. The latter further shows that the antenna sockets contain a directional coupler and filter.
  • an antenna socket is provided with a third connection, which is used to feed back channel signals to the center of a cable television system.
  • signals are used in television, radio broadcasting, text and image distribution, warning services, subscriber signals, remote measurement, monitoring, local programs, order service, information service, library service, interactive services, inventory management and of interest in remote data processing.
  • the invention has for its object to realize such a third connection using conventional antenna sockets.
  • this object is achieved according to the invention in that the through line output of the directional coupler is connected to the inputs of the bandpass filter and the bandstop filter and that the output of the coupling loop of the directional coupler is connected to the second connection.
  • the socket wired according to the invention represents a stub line socket, via whose "" outgoing "coaxial line additional signals can be fed in or taken out.
  • additional signals can be fed in or taken out.
  • carrier-frequency digital signals can be used for addressing subscribers.
  • The" "outgoing" coaxial line then leads to a modem.
  • the frequency of the signals fed in can be below 40 MHz; the extracted signals can occupy the frequency band from 40 to 860 MHz.
  • the directional coupler can be designed as a crossover circuit.
  • Fig. 1 shows the antenna socket known from the aforementioned DE-PS 27 33 220. This contains a first connection 7 for a first coaxial cable, a first coaxial socket 2, a second coaxial socket 3 and a second connection 4 for a second coaxial cable.
  • the two coaxial cables are shown under a hinged clamp.
  • the reference lines from the reference numerals 1 and 4 indicate where the coaxial cables are located under the hinged clamp.
  • Fig. 2 shows the known wiring of the box of Fig. 1 as a through box.
  • This contains a directional coupler 5 for 40 to 860 MHz, a bandstop filter 6 for radio broadcast signals and a bandpass filter 7 for radio broadcast signals.
  • the antenna signals pass through the socket unchanged from connection 1 to connection 4.
  • TV signals are present at the coaxial socket 2 without radio broadcast signals and at the coaxial socket 3 only radio signals are present.
  • Fig. 3 shows the wiring of the box according to Fig. 1 as a branch line box.
  • the directional coupler 5 and a coaxial cable for antenna signal transmission are unnecessary.
  • the inputs of the bandstop filter 6 and the bandpass filter 7 are connected directly to the coaxial cable connection 1.
  • Fig. 4 shows the circuitry of the socket I according to the invention.
  • a directional coupler 5 'for 5 to 860 MHz is interposed between the coaxial cable connection 1 and the inputs 10 of the bandstop filter 6 and the bandpass filter 7.
  • the output 11 of the coupling-out loop of the directional coupler 5 ' is connected to the connection 4.
  • connection 4 now offers a connection option for devices of additional services that emit signals both in the reverse direction and possibly also from the System distribution direction can record additional signals, such as carrier-frequency digital signals, for subscriber addressing.
  • Connection 4 can be used to establish a connection to a modem which receives the carrier frequency additional signals in the forward direction, which can be transmitted, for example, in the frequency range 40 to 860 MHz, and feeds carrier-frequency additional return signals below 40 MHz into the system.
  • the broadband directional coupler 5 'offers the advantage of the mutual decoupling of television (TV) or radio broadcasting devices (R) connected to the coaxial sockets 2 and 3 and the device for additional services (RK).
  • FIG. 5 shows an arrangement corresponding to the arrangement according to FIG. 4 with a transformer coupler 5 ".
  • the directional coupler 5 'can also be designed as a crossover circuit.
