Regular maintenance is critical to ensuring our communication infrastructure performs reliably year-round. As part of our 2024 service schedule, our team conducted a detailed inspection and maintenance session across three key antennas on site. Here’s a breakdown of the findings, repairs, and recommendations.

All three antenna dishes were thoroughly cleaned and found to be in serviceable condition. Annual cleaning helps preserve surface integrity and maintain signal quality.

Identified Faults and Corrective Actions

During the visit, several issues were identified and immediately addressed:

1. Surface Rusting
   Minor surface rust was discovered on the azimuth screw jack tube, antenna pedestal base, sub-reflector spar arms, and control panel. These areas were treated and protected using a cold galvanising spray to prevent further corrosion.

2. Loose Lightning Conductor
   The lightning conductor cable had come loose from the hub diameter. It was securely refitted using durable cable ties.

3. Missing Cable Ties
   The retaining clips on both mains and secondary supplies to the axis motor drives were missing all tie wraps. All necessary cables were re-secured with appropriate cable ties.

Further Observations

We noted that the secondary cables supplying the axis drive motors show early signs of degradation on the outer sheath. While the system remains operational, we recommend replacing these cables within the next two years to avoid potential issues.

Equipment-Specific Maintenance

Precision 2.2M Motorized Antenna (Type E22)

• All hardware was checked and tightened.

• Cables were inspected and found to be in good condition.

• The antenna dish was cleaned.

• Azimuth Drive: Super Power Jack – QARL-3636+, 36V DC, SN: 20200600309
  All fastenings were confirmed secure.

Precision 1.5M Fixed Antenna

• All hardware and cabling were checked and tightened.

• The dish was cleaned.

• The lightning conductor was observed to be loose and will be monitored.

Conclusion

All antennas were deemed fully operational and in good condition following the 2024 maintenance service. The annual clean and detailed inspection contributed to maintaining performance standards and equipment longevity.

We will issue a quotation to replace the secondary cabling in advance of the 2025 service date.
