Replacing antenna cables
Replacing antenna cables
A new concept in repairs has been developed to repair antenna cables. Connection cables with differing lengths and different adapters are available as replacement parts to replace complete conventional antenna cables.
General description:
t  Antenna cables must not be repaired. They should be replaced exclusively by connection cables and adapters belonging to the range of genuine replacement parts → Communication; Rep. gr.91.
t  Replacement parts can be found listed in the → Electronic Parts Catalogue „ETKA“.
t  The connector terminals of the antenna cables are available as replacement parts in one color only. However, they may be used for all colors of connectors.
t  The replacement of isolated antenna connectors is not allowed for in case of repair.
t  The connection cables should be used from now on in all VW models, with all diameters of antenna cable.
t  All adapters and connection cables are suitable for all transmission and reception signals.
t  The repair concept may also be used for verification of later assembly.
   
General overview of antenna cable assembly
Example: a broken radio antenna cable. The following cables are required to carry out the repair:
1 - Adaptation cable for connection to the radio; approx. length 30 cm.
2 - Connection cable, available in different lengths.
3 - Adaptation cable for connection to the antenna; approx. length 30 cm.
Assembly of a new antenna cable:
  Note
Depending on the equipment in the vehicle, the total length of an antenna cable may be divided into partial sections by the antenna control units of the traffic information system or antenna amplifiers. Replace the damaged section only.
–  Disconnect the damaged antenna cable connectors from their respective units.
–  Determine the trajectory of the damaged antenna cable and measure the total length of the antenna cable to be installed in the vehicle.
  N97-0424
The total length of the antenna cable depends on the length of the necessary antenna adaptation cables -1- and -3- , as well as the connection cable -2-.
–  Subtract 60cm of the total determined length of the antenna cable, thus obtaining the necessary length for the connection cable -2-.
–  Request the necessary adaptation cables -1- and -3- and the connection cable -2- with the length calculated for the replacement parts, according to the parts catalogue.
–  Cut the cable connectors of the damaged antenna cable.
The remains of the damaged antenna cables will stay in the vehicle.
–  Connect the adaptation cables -1- and -3- to the units of the vehicle.
–  Install the connection cable -2- near the original position of the antenna cable of the vehicle.
  Note
Antenna cables must not be obstructed or excessively stranded. Curvature must not exceed 50mm.
–  Connect the connection cable -2- to the adaptation cables -1- and -3-
–  Check that the system works correctly.
