The 3014 (30 × 14mm) and 4008 (40 × 8mm) are better suited for space-constrained devices. The 6615's dual-point VSWR verification (≤1.5 at both 2.4GHz and 2.5GHz) also makes it a reliable choice for multi-protocol devices using WiFi, Bluetooth, and ZigBee simultaneously.\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: Which 2.4GHz protocols does the TX2400-FPC-6615 support?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: The 2.4–2.5GHz frequency range covers WiFi 802.11b\/g\/n (2.412–2.484GHz), Bluetooth Classic and BLE 5.x (2.402–2.480GHz), ZigBee 3.0 (2.405–2.480GHz), Thread, Matter, and proprietary 2.4GHz FSK\/GFSK protocols. The dual-point VSWR verification at 2.4GHz and 2.5GHz confirms consistent impedance matching across all these protocols simultaneously.\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: Can this antenna be installed inside a metal enclosure?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: No. Placing any FPC antenna inside a metallic housing causes severe signal attenuation due to RF shielding. The TX2400-FPC-6615 must be mounted on the inner surface of a non-metallic (ABS, PC, or TPEE) enclosure with a minimum 3mm clearance from metal components. For metal enclosures, use an external 2.4GHz antenna with a bulkhead SMA connector routed through a feedthrough.\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: How do I mount the TX2400-FPC-6615 and what clearances are required?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: Peel the 3M adhesive backing and press the 66 × 15mm FPC flat against the inner wall of a non-metallic enclosure. Keep the antenna at least 3mm from the PCB ground plane, battery, and metal shielding cans. Route the 120mm coaxial feeder to your 2.4GHz module's IPEX-I socket and press-fit the connector until it clicks. For the 66mm length, ensure the mounting surface is flat or has a gentle curve radius \u0026gt;50mm to avoid delamination of the adhesive backing.\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: What is the operating temperature range and is it suitable for outdoor IoT deployments?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: The TX2400-FPC-6615 is rated for -40°C to +85°C. The FPC substrate is RoHS-compliant and resistant to humidity under standard operating conditions. For outdoor deployments, ensure the host enclosure provides IP65 or higher sealing. The antenna itself is not independently IP-rated and must be protected by the device enclosure from direct rain, UV exposure, and condensation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n","brand":"cdsenet","offers":[{"title":"Default Title","offer_id":45301875769446,"sku":"10*TX2400-FPC-6615","price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/9918\/9350\/files\/TX2400-FPC-6615-_1_800x800_v2.jpg?v=1773986454","url":"https:\/\/cdsenet.store\/products\/tx2400-fpc-6615-2-4ghz-wifi-bluetooth-fpc-antenna-3-5dbi","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
