Properties of the SINAUT components
1.6 Radio clock components
Since the GPS antenna is an outdoor antenna, you should also install the available lightning
protection device.
Figure 1-37
The following figure shows the interconnection of the various GPS components (the adapter
cable 6NH7700-0AD15 is supplied with each TIM with an integrated DCF77 radio clock
receiver).
If lightning protection 6NH9831-8LA is used, this should be installed whenever possible at
the entrance to the building. To connect the lightning protection to the adapter cable of the
TIM, use a separate antenna cable (BNC female connectors at both ends, similar to the
antenna cable supplied with the outdoor antenna). You can either assemble this cable
yourself or purchase it from a dealer, for example from Hopf Elektronik GmbH
(www.hopf.com).
