Intellian VSAT Ka-Band 130cm-C

Common issues

• Radome degradation from UV/weathering, reducing signal transmission efficiency
• LNB/BUC failure from moisture ingress or age
• Stabilization/tracking motor wear affecting pointing accuracy in heavy seas
• Waveguide or cable connector corrosion causing signal loss
• ACU (antenna control unit) software/firmware issues causing loss of satellite lock
• Azimuth/elevation drive bearing wear from continuous motion compensation

Inspection checklist

• Inspect radome condition (cracks, discoloration, water ingress)
• Check RF cable connectors and waveguide for corrosion or moisture
• Verify signal strength/quality against baseline
• Test tracking and stabilization response during vessel motion
• Check ACU software/firmware version
• Inspect drive motor and gearing for wear or noise
• Check grounding/bonding integrity for lightning protection

Service intervals

Typical wear limits

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

• LNB (Low Noise Block)
• BUC (Block Up-Converter)
• RF cable/connector kit
• Radome
• Antenna Control Unit (ACU)

Safety

• RF exposure near the feed/BUC during transmission - respect the maker's stated exclusion zone
• Working aloft/at height for radome or antenna access requires fall protection
• Lightning strike risk to the elevated antenna structure

Class survey

Where the terminal forms part of the vessel's GMDSS fit, periodic functional testing applies and is typically covered under the Radio Survey; flag/class expect evidence of annual servicing and correct entries in the radio log/GMDSS equipment record.
