White Coaxial Cable: A Finish Choice
Quick answer / TL;DR: Short answer: white is a jacket colour only. Check the specification separately for 75 ohm impedance, shield construction, fire rating and UV resistance. Standard white PVC is for interior runs; outdoor routes need a UV-rated jacket or conduit.
Colour is a label, not a specification: the jacket print still decides.White coax exists for interior aesthetics: skirting boards, light walls and visible runs in a living room.
The colour says nothing about shielding, impedance or suitability for outdoor use.
What Colour Does Not Tell You
| Property | Set by colour | Set by specification |
|---|
| Impedance | No | 75 ohm rating |
| Shielding | No | Braid and foil layers |
| UV resistance | No | Jacket compound |
| Fire rating | No | CL2, CL3 or plenum |
A white jacket on an indoor PVC cable will discolour and crack outdoors within a season or two.
Finishing Practice
- Clip rather than staple to avoid crushing the dielectric
- Use white clips for a clean run
- Avoid solvent paint on PVC
- Keep bends gentle at the wall entry
- Label both ends behind furniture
Staples are the most common cause of a crushed coax: the impedance changes locally and the link degrades at high frequency.
Real-World Applications
A white cable along a light skirting from a wall plate to a television is the intended use. An outdoor run to a dish needs a black UV-rated jacket or conduit, regardless of how visible it is.
Standards and Verification
| Reference | Relevance |
|---|
| IEC 61196 | Coaxial cable |
| UL 444 | Communications cable |
| SCTE | Installation practice |
UV performance for a specific jacket is not provided in the knowledge base. Check the manufacturer's rating.
Practical Notes
Keep one white and one black reel separate. Mixing them outdoors is a common and avoidable failure.

Frequently Asked Questions
Is white cable outdoor rated?
Not unless the jacket states UV resistance.
Does colour affect signal?
No.
Can I paint it?
Only with paint that does not attack PVC.
