Cable coiling is a method of storing cables, specifically using the over/under technique, designed to preserve the cable's original electrical properties and prevent damage. This technique is crucial for maintaining the integrity of cables used in professional audio, video, and data applications.
Understanding Over/Under Cable Coiling
The over/under coiling method involves alternating loops in opposite directions (one "over," the next "under") as you wind the cable. This prevents the cable from twisting upon itself, which can lead to kinks, knots, and ultimately, damage.
Why is Cable Coiling Important?
- Preserves Electrical Characteristics: Over/under coiling helps maintain the intended capacitance and common-mode rejection ratio built into the cable during manufacturing. This is particularly important for shielded cables carrying sensitive signals.
- Prevents Damage: By avoiding twists and kinks, over/under coiling extends the lifespan of the cable and reduces the likelihood of signal degradation.
- Easier Uncoiling: Cables coiled using the over/under method uncoil smoothly and without tangles, saving time and frustration during setup and teardown.
How to Coil a Cable Using the Over/Under Method
- Start with a Straight Cable: Ensure the cable is free of twists and kinks.
- Create the First Loop: Form a loop in your hand. This is the "over" loop.
- Create the Second Loop: Twist the cable 180 degrees in your hand. This creates the "under" loop.
- Repeat: Continue alternating "over" and "under" loops, keeping them roughly the same size.
- Secure the Coil: Use a cable tie, Velcro strap, or the cable's built-in strap to secure the coiled cable.
Benefits of Using the Over/Under Method
- Reduces Stress: Minimizes stress on the cable's conductors and shielding.
- Increases Longevity: Extends the usable life of the cable.
- Professional Appearance: Provides a neat and organized way to store cables.
- Faster Deployment: Simplifies and speeds up cable deployment and retrieval.
When to Use Over/Under Coiling
The over/under method is recommended for almost all types of cables, especially:
- Microphone cables (XLR cables)
- Instrument cables (1/4" cables)
- Network cables (Ethernet cables)
- Speaker cables
- Any shielded cable carrying audio, video or data signals.
By implementing the over/under coiling technique, you can ensure your cables remain in excellent condition, preserving their performance and extending their lifespan.
