Antenna Carriers - Defect causes and influences on construction

Basic information

Locations

• Antenna carriers at several mobil phone locations

Features

• Fatigue break of carriers with sector antennas

Process

• 2005

Tasks and results

Inspection of conduit break locations and investigation of boundary conditions

• Location type (mast, building, etc.)
• Carrier construction (slenderness, etc.)
• Miscellaneous (wind conditions, arrangement of carriers to each other, etc.)

Evaluation of defect causes via

• Determination of steel material
• Reproduction of dynamic strain

Verification of the results by investigation of stock

• Attenuation evaluation of similar antenna carriers
• Natural frequency determination of comparable antenna carriers
