Peel the adhesive backing and press the FPC antenna firmly onto a flat or gently curved non-metallic (plastic or PCB) surface. Maintain at least 5 mm clearance from metal components or ground planes to prevent detuning. Route the 120 mm cable without sharp bends (minimum bend radius: 5 mm) and snap the IPEX-1 connector onto the module's U.FL port until it clicks.
