High-Quality Cable: 1.13mm diameter RG178 coaxial cable with fluorinated ethylene propylene (FEP) insulation for flexibility, durability, and minimal signal loss (max 1.5dB @ 6 GHz).
Panel-Mount Design: Screw-threaded SMB male connector securely fastens to metal enclosures or PCB panels — eliminates strain on internal RF traces.
25cm Pigtail Length: Ideal for routing antennas away from interference-prone circuit boards while maintaining signal integrity.
Rated for 30 Cycles: Designed for occasional connection/disconnection during prototyping or maintenance — avoid repeated mating to preserve connector life.

Prototyping and RF test setups requiring secure panel mounting
Do not force the U.FL connector. It snaps in with light pressure — a distinct “click” confirms proper engagement.
Use tweezers or a non-metallic tool to handle the U.FL end — avoid finger contact with the center pin.
Secure the cable along the chassis with zip ties or adhesive clips to prevent flex fatigue near the connector.
Not recommended for high-vibration environments without strain relief.
Unlike generic jumpers, this cable is engineered for industrial-grade reliability — not just low cost. The SMB panel mount ensures mechanical stability, while the RG178 cable balances flexibility and attenuation performance. Perfect for OEMs, system integrators, and makers deploying wireless solutions in space-constrained enclosures.
