Connect the RF1.13 coaxial cable directly to the IPEX-1 generation antenna receptacle on your cellular module (such as Ebyte 4G\/5G DTUs and wireless transmission modules) with vertical alignment until fully seated.\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/1_10_95a3538b-5da2-49ac-b567-24ed7ed3b80a.jpg?v=1793699438\" alt=\"Ebyte TX4G\/TX5G Series Antenna Dimensions \u0026amp; IPEX Connector - 1_10.jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/1_11_1ac2f84d-f005-4470-9120-e04a50f085dc.jpg?v=1793699439\" alt=\"Ebyte TX4G\/TX5G Series Antenna Dimensions \u0026amp; IPEX Connector - 1_11.jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/1_12_8e86179a-a6ba-41b7-abb2-e02e4c550015.jpg?v=1793699439\" alt=\"Ebyte TX4G\/TX5G Series Antenna Dimensions \u0026amp; IPEX Connector - 1_12.jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/1_13_7a4bd47a-3e90-4e4a-a8ed-33ec83a2ee90.jpg?v=1793699439\" alt=\"Ebyte TX4G\/TX5G Series Antenna Dimensions \u0026amp; IPEX Connector - 1_13.jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cdiv class=\"ebyte-text-specs\" style=\"margin-top: 30px;\"\u003e\n\u003ch2\u003ePractical Application Scenarios\u003c\/h2\u003e\n\u003ch3\u003e1. Industrial 4G\/5G IoT Cellular Routers \u0026amp; Remote Communication Gateways\u003c\/h3\u003e\n\u003cp\u003eIn smart grid distribution boxes, water treatment plants, and solar telemetry stations, compact cellular DTUs and industrial edge computing gateways require embedded antennas to maintain high ingress protection (IP65\/IP67) ratings without external antenna protrusions. Integrating TX4G-FPC-8121 or TX5G-FPC-9016 antennas inside plastic gateway housings provides stable, omnidirectional cellular uplinks for remote PLC monitoring and Modbus telemetry.\u003c\/p\u003e\n\u003ch3\u003e2.

How does an FPC internal antenna compare to traditional external whip antennas?\u003c\/h3\u003e\n\u003cp\u003eFPC antennas are embedded directly inside device enclosures, eliminating external antenna rods that are prone to accidental breakage, vandalism, or water leakage. With high 5dBi peak gain, optimized FPC antennas achieve comparable communication performance to external rubber duck antennas while maintaining an aesthetically clean, ruggedized enclosure.\u003c\/p\u003e\n\u003ch3\u003e2. Can the TX5G-FPC-9016 antenna be used for 4G LTE and 2.4GHz Wi-Fi applications?\u003c\/h3\u003e\n\u003cp\u003eYes. The TX5G-FPC-9016 is an ultra-wideband antenna engineered for 690MHz to 7000MHz. It natively covers legacy 2G\/3G, all mainstream 4G LTE bands, 2.4GHz\/5.8GHz Wi-Fi, and global 5G Sub-6GHz cellular frequency bands (including n1, n28, n41, n77, n78, n79).\u003c\/p\u003e\n\u003ch3\u003e3. What installation precautions must be taken to prevent cellular signal degradation?\u003c\/h3\u003e\n\u003cp\u003eNever paste the FPC antenna onto metallic surfaces or near large metal components (such as shielding cans, batteries, or ground pours), as metal will detune the antenna resonance and severely reduce radiation efficiency. Maintain at least 10mm to 15mm clearance between the antenna radiating element and any conductive metal.\u003c\/p\u003e\n\u003ch3\u003e4. Is the coaxial cable length and connector type customizable for OEM projects?\u003c\/h3\u003e\n\u003cp\u003eYes. While standard models feature 109mm or 120mm RF1.13 coaxial cables with IPEX-1 generation connectors, Ebyte provides custom cable lengths (e.g., 50mm to 300mm), alternative coaxial line gauges (RF0.81 \/ RF1.37), and different micro-RF connectors (IPEX-4 \/ MHF4, SMA, U.FL) for volume OEM\/ODM manufacturing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Ebyte Official Store - IoT Module Manufacturer","offers":[{"title":"TX4G-FPC-8121","offer_id":48849233936589,"sku":"TX4G-FPC-8121","price":0.47,"currency_code":"USD","in_stock":true},{"title":"TX5G-FPC-9016","offer_id":48849233969357,"sku":"TX5G-FPC-9016","price":0.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/1_6a4aecd4-db70-488a-a5ed-b4df32d176a5.jpg?v=1793699455","url":"https:\/\/ebyteiot.com\/pt\/products\/tx4g-tx5g-series-4g-5g-fpc-internal-antenna-5dbi-ipex","provider":"Ebyte Official Store - IoT Module Manufacturer","version":"1.0","type":"link"}
