Introduction
High-frequency cables, especially those used in microwave and RF measurement systems, are precision-engineered components. Their electrical stability depends not only on design but also on how they are handled and stored. Improper storage can lead to phase instability, connector damage, or increased insertion loss over time.

Maintain a Controlled Environment
Keep cables in a dry, dust-free area with stable temperature and humidity.
Avoid direct sunlight, excessive heat, or cold storage areas, as temperature cycling can cause micro-expansion and contraction of conductors.

Use Proper Winding Techniques
Always store cables in loose, natural coils with a bend radius larger than the manufacturer’s minimum specification.
Tight wrapping or sharp bends can permanently deform the dielectric or shield layer.

Protect Connectors
Connector ends are the most sensitive parts of high-frequency assemblies.
Use protective caps to prevent dust ingress or mechanical wear, and avoid placing weight on the connectors.

Label and Organize by Frequency Range
If multiple cables are used in a lab, store them by frequency range or model number.
This prevents mix-ups between high-precision and general-purpose assemblies.

Regular Inspection and Cleaning
Before reuse, visually inspect the connectors and outer jacket for signs of corrosion or deformation.
Clean gently with isopropyl alcohol and lint-free wipes to maintain signal integrity.

Conclusion
Proper storage extends not only the cable’s physical lifespan but also its electrical stability and repeatability in measurements.
By adopting correct handling and storage practices, engineers can ensure consistent performance even in demanding RF environments.
