Overview
Understand U.FL / IPEX cable loss and when tiny RF pigtails hurt antenna range.
Key points
- Keep U.FL pigtails short.
- Avoid repeated reconnecting because tiny connectors wear out.
- Use correct connector type and cable impedance.
- For long runs, transition to SMA and lower-loss coax.
Practical advice
RF cable choice can strongly affect real range. At 2.4 GHz and 5 GHz, even short poor-quality cables can lose significant power.
Common mistakes
Common mistakes include using long thin coax, adding too many adapters, confusing SMA and RP-SMA, and ignoring cable loss in the link budget.
