7 Connect and Manage Cables
7.1 Connect HiperMAX
1. Run the cable from the Antenna to the GPS Shelf and attach to the GPS Antenna port and
attach to the GPS Antenna.
2. Neatly tie any excess cable (see Secure Fibre-optic Cable in the Appendix for this guide).
7.2 Connect Optic interface for HiperMAX-micro
Each SCRT is provided with a 3 metre optical fibre cable, ready terminated with optical connectors.
Unscrew the protective dust cap and screw the fibre optic cable in place.
7.3 Connect Optic interface for HiperMAX ATCA
Each SCRT is connected with optical fibre cable, ready terminated with optical connectors. Unscrew
the protective dust cap and screw the fibre optic cable in place.
7.4 Install GPS Antenna
Checkpoint: If the HiperMAX-micro GPS is specified for this installation, follow
this instruction. Otherwise exit this instruction and proceed to the next one.
7.4.1 Install GPS antenna for HiperMAX-micro
SDR-micros that have the GPS option have a GPS antenna and four metres of
cable included.
Install the GPS antenna for the HiperMAX-micro using a 4 m standard cable and optional pole mount
bracket.
The first consideration for a GPS antenna is a clear view of the sky, preferably 360 degrees. In the
usual installation, the GPS antenna is located low and close to the equipment building roof. The GPS
antenna should be attached to a suitable mast and connected at the base of the SDR-micro.
Use the guidance below to find the optimal position for mounting the GPS antenna:
a) The antenna must be mounted in an upward position.
b) The antenna should be installed at the highest possible point available at the site. This is to ensure
minimum obstruction from any surrounding obstacles (trees, buildings or other installations, etc.).
c) To avoid influence of reflected waves, the antenna must not be installed less than 2m away from
metallic objects with a dimension greater then 20 cm.
