The ADU system must be mounted inside the building and connected to the Meinberg GPS converter antenna via a coaxial cable.
The GOAL-S-R module is connected on receiver side to the GPS antenna input of the receiver via a coaxial cable and can be mounted close to the connected receiver.
The two modules (ADU and GOAL-S-R) are interconnected via E9/125µm single-mode fiber. This type of antenna connection has the following advantages:
- long antenna cable runs possible (up to 10km)
- no danger caused by overvoltage damage via the antenna cable
- tap-proof security communication through fiber optic connection
The GOAL-S/R modules installed on receiver side are powered by the Meinberg GPS-IF receiver via coaxial cable. The ADU/FOS/MP system installed on antenna side requires an externally supplied voltage for its own power supply as well as for feeding the connected antenna through the built-in GPS receiver.
The system is suitable for the subsequent extension of existing Meinberg GPS systems. The following GPS receivers are suitable for use with a GOAL-S Antenna Link:
and older receivers of the series GPS163, GPS164, GPS165, GPS167, GPS168, GPS169 and GPS170 (but not GPS166!).
