Avoid routing the 120 mm feeder cable parallel to the FPC element, as coupling can increase VSWR and reduce effective gain.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"margin-bottom: 20px; padding: 15px; background: #fafafa; border-radius: 8px;\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 6px;\"\u003eQ: What is the operating temperature range and environmental suitability?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: The TX2400-FPC3-5015 is rated for −40 °C to +85 °C, suitable for indoor consumer electronics, smart home devices, and light industrial environments. The FPC substrate is RoHS-compliant. For high-humidity deployments, apply conformal coating over the FPC radiating element or house it inside a sealed IP-rated enclosure to prevent moisture-induced detuning.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"padding: 15px; background: #fafafa; border-radius: 8px;\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 6px;\"\u003eQ: Can the 120 mm feeder cable length be customized for OEM production?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: Yes. The standard feeder is 120 mm RG0.81 coaxial cable, introducing \u0026lt; 0.4 dB insertion loss at 2.45 GHz. Custom lengths are available for OEM orders — shorter cables reduce loss further, while cables up to ~200 mm add approximately 0.3–0.6 dB additional loss at 2.4 GHz.
