The presence of one or more S or X-band radars within a radius up to 100m may cause a minor degradation
of the Ku-band connection. The degradation will be most significant at high radar pulse repetition rates.
Especially in poor receiving conditions (objects blocking the signal path, heavy rainfall or icing, low satellite
elevation and violent ship movements) the small extra degradation due to the radar(s) could cause poor
connection quality.
4.3 Planning the cable paths
Please check which walls are suitable and if existing openings can be used for the cables. Laying the cables
is usually done by an electrician in the dockyard with proper certificates to alter the ships installations or the
ships structure. If you're in charge of laying the cables, make sure it is done in accordance with the following
rules:
•
Use suitable coax cables: double shielded EcoFlex 10 or 15 is recommended. EPAK warranty does
not cover decreased performance due to improper wiring.
•
The maximum recommended cable length for EcoFlex10 is 50 m and Ecoflex15 is 80 m. Make sure
that the cable length does not exceed this value. If maximum cable length is too short for your
installation, favour higher grade cables over in-line amplifier.
•
Avoid placing RF cables too close to other cables which might carry "noise".
•
Fit and secure cables properly. Use shrink tubing with heat activated adhesive to seal connectors.
•
Avoid sharp bends and kinks on cables.
•
To connect antenna and ACU, use cables in one piece; do not extend cables, do not split cables.
•
Use only high quality RF connectors.
4.4 Drilling
For an ideal mounting of the antenna all possible drilling patterns are prepared with a pre-drilled hole of 2 mm
in the bottom of the radome. Please refer to the included templates for the drilling measurements. The drilling
should have a diameter of Ø 8.5 – 9 mm for the included M8 screws. It is recommended to start with a
smaller hole, using a Ø 3.5 – 4 mm drill to avoid any damage to the mounting surface. To mount the antenna,
only use the included M8 mounting screws.
