An FPC antenna uses a flexible substrate that can conform to curved surfaces and is easier to route in irregular enclosures. Choose PCB (TX433-PCB-3207) when dimensional stability and vibration resistance are priorities; choose FPC (TX433-FPC-4516 \/ TX433-FPC-5711) when flexible mounting or curved surfaces are required.\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 PCB or FPC antenna inside a metallic housing causes severe signal attenuation due to RF shielding. The TX433-PCB-3207 must be mounted inside a non-metallic (ABS, PC, or TPEE) enclosure with a minimum 5mm clearance from any metal component. For metal enclosures, use an external antenna with a bulkhead SMA connector instead.\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 TX433-PCB-3207 inside my device?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: The PCB radiator can be secured using a mounting hole (if present on the PCB) or a double-sided adhesive pad on the non-copper side. Route the 90mm coaxial feeder to your module's IPX-I socket and press-fit the connector until it clicks. Ensure the antenna is positioned parallel to the enclosure wall and away from battery packs, metal shielding cans, and other RF-absorbing components. No soldering is required.\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 environmental durability?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: The TX433-PCB-3207 is rated for -40°C to +85°C, covering industrial and outdoor deployment scenarios. The PCB substrate is RoHS-compliant. The rigid PCB construction is more resistant to deformation from thermal cycling than FPC alternatives, making it suitable for applications with wide temperature swings. For direct outdoor exposure, ensure the host enclosure provides adequate IP-rated sealing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n","brand":"cdsenet","offers":[{"title":"Default Title","offer_id":45205439348838,"sku":"10-tx433-pcb-3207","price":4.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/9918\/9350\/files\/TX433-PCB-3207-_3_800x800_v2.jpg?v=1773475063","url":"https:\/\/cdsenet.store\/products\/tx433-pcb-3207-433mhz-pcb-antenna-2-0dbi-ipx-i","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
