High-quality low-loss feeders cannot deliver expected network performance if installed with non-standard operations. Many signal faults detected during 5G network testing trace back to improper feeder laying, connector assembly and fixing methods. We sort out five frequent installation mistakes and standardized solutions for field construction teams.
Exceeding Minimum Bending Radius Requirement: Sharp bending squeezes the internal insulation layer, deforming copper conductors and sharply boosting signal loss. Construction staff must follow the manufacturer’s specified bending radius; avoid tight bending at tower corners and pipeline outlets.
Unsealed Feeder Connectors: Poor waterproof wrapping of male/female joints allows rainwater and moisture to penetrate the conductor. Oxidation inside connectors creates extra loss and intermittent signal disconnection. All outdoor joints require multi-layer waterproof tape and protective sleeves.
Over-Tightened Cable Clamps: Excessive clamping force crushes the feeder outer sheath and shielding layer, damaging internal structure. Soft rubber buffer gaskets should be used for all fixed clamps to reserve space for thermal expansion and contraction.
Mixed Layout with High-Voltage Power Cables: Parallel laying of feeders alongside power lines introduces strong electromagnetic interference, distorting 5G communication signals. Maintain a safe separation distance, or use partition pipeline separation during wiring.
Unnecessary Over-Length Wiring: Many engineers reserve excessive redundant feeder length on towers and ceilings. Extra cable sections stack up signal attenuation, raising power consumption and interference risks. Cut feeders to reasonable lengths according to actual measured distances before connector assembly.
