The 50¦¸ impedance matches standard WiFi chipsets. Verify your module uses IPEX-1 connector (not IPEX-4 MHF4 which requires an adapter). Compatible with modules operating at 2.4GHz (802.11b\/g\/n) and 5GHz (802.11a\/n\/ac) frequencies.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 25px; border-bottom: 1px solid #eee; padding-bottom: 20px;\"\u003e\n\u003cp style=\"font-weight: bold; font-size: 16px; margin-bottom: 8px; color: #111;\"\u003eQ: How do I install this FPC antenna inside a device enclosure?\u003c\/p\u003e\n\u003cp style=\"color: #555; margin: 0; font-size: 15px; line-height: 1.7;\"\u003eA: The flexible PCB design allows mounting using adhesive backing (3M VHB tape recommended) or mechanical clips. Position the 38mm ¡Á 10mm radiator element at least 10mm away from metal surfaces to prevent detuning. For plastic enclosures (ABS, PC, PMMA), mount the antenna flat against the interior wall. Route the 120mm feeder cable away from high-current traces, switching power supplies, and LCD displays to minimize EMI. The IPX connector requires 2-3N insertion force and should click audibly when properly seated. Avoid sharp bends in the feeder cable (minimum bend radius: 5mm).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 25px; border-bottom: 1px solid #eee; padding-bottom: 20px;\"\u003e\n\u003cp style=\"font-weight: bold; font-size: 16px; margin-bottom: 8px; color: #111;\"\u003eQ: What is the operating temperature range and environmental durability?\u003c\/p\u003e\n\u003cp style=\"color: #555; margin: 0; font-size: 15px; line-height: 1.7;\"\u003eA: The TXWF-PCB-3810 operates reliably across \u003cstrong\u003e-40¡ãC to +85¡ãC\u003c\/strong\u003e ambient temperature range, suitable for industrial and automotive applications. The FPC substrate maintains stable electrical characteristics across this range with \u0026lt;0.2dB gain variation. While the antenna itself has no IP rating (designed for internal mounting), the materials are RoHS compliant and resistant to humidity up to 95% RH non-condensing. For outdoor applications, mount inside a weatherproof enclosure with RF-transparent window (polycarbonate or ABS recommended).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 25px; border-bottom: 1px solid #eee; padding-bottom: 20px;\"\u003e\n\u003cp style=\"font-weight: bold; font-size: 16px; margin-bottom: 8px; color: #111;\"\u003eQ: What wireless range can I expect with this 2.0dBi antenna?\u003c\/p\u003e\n\u003cp style=\"color: #555; margin: 0; font-size: 15px; line-height: 1.7;\"\u003eA: Range depends on transmit power, receiver sensitivity, and environment. With typical 20dBm (100mW) WiFi modules at 2.4GHz, expect \u003cstrong\u003e50-100m indoor range\u003c\/strong\u003e (through 2-3 walls) and \u003cstrong\u003e200-300m line-of-sight outdoor\u003c\/strong\u003e. At 5.8GHz, range reduces by approximately 30% due to higher path loss. The 2.0dBi gain provides balanced omnidirectional coverage (¡À30¡ã elevation beamwidth) suitable for gateway and sensor applications. For extended range, consider pairing with a higher-gain external antenna (5-9dBi) or increasing transmit power within regulatory limits (FCC: 30dBm EIRP max for 2.4GHz).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 25px;\"\u003e\n\u003cp style=\"font-weight: bold; font-size: 16px; margin-bottom: 8px; color: #111;\"\u003eQ: Does this antenna require FCC or CE certification for my product?\u003c\/p\u003e\n\u003cp style=\"color: #555; margin: 0; font-size: 15px; line-height: 1.7;\"\u003eA: The antenna itself does not require separate certification, but your complete wireless device must undergo FCC Part 15 (USA), CE RED (Europe), or equivalent regional testing. This antenna's measured performance data (gain, VSWR, radiation pattern) can be submitted as part of your device's certification documentation per 3GPP TS 34.114 and ETSI EN 300 328 standards. The antenna is designed to support compliance testing with VSWR ¡Ü1.5 ensuring minimal harmonic radiation. For intentional radiators, you may use FCC modular approval if your WiFi module is pre-certified and the antenna gain does not exceed the module's certified gain by \u0026gt;3dBi.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"cdsenet","offers":[{"title":"Default Title","offer_id":44909224886374,"sku":"txwf-pcb-3810","price":0.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/9918\/9350\/files\/TXWF-PCB-3810-_1_800x800_v2.jpg?v=1773047363","url":"https:\/\/cdsenet.store\/products\/txwf-pcb-3810-dual-band-wifi-antenna","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
