The 700–2700MHz coverage includes the primary NB-IoT and LTE-M deployment bands globally: Band 20 (800MHz, Europe), Band 28 (700MHz, Asia-Pacific), Band 8 (900MHz), Band 3 (1800MHz), and Band 1 (2100MHz).

The TX4G-PCB-6613 is recommended when low-band LTE performance (Band 20\/28 for NB-IoT, or Band 5\/8 for rural LTE coverage) is a priority. For enclosures where 66mm length is not feasible, the TX4G-PCB-4410 (44 × 10mm) is the compact alternative.\u003c\/p\u003e\n    \u003c\/div\u003e\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      \u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: No. Placing any PCB antenna inside a metallic housing causes severe signal attenuation due to RF shielding. The TX4G-PCB-6613 must be mounted inside a non-metallic (ABS, PC, or TPEE) enclosure with a minimum 5mm clearance from metal components. For metal enclosures, use an external LTE antenna with a bulkhead SMA or TNC connector routed through a feedthrough.\u003c\/p\u003e\n    \u003c\/div\u003e\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 and connect the TX4G-PCB-6613?\u003c\/p\u003e\n      \u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: Secure the 66 × 13mm PCB radiator to the inner wall of a non-metallic enclosure using a mounting hole or double-sided adhesive pad on the non-copper side. Route the 120mm coaxial feeder to your LTE or NB-IoT module's IPX-I (U.FL) antenna port and press-fit the connector until it clicks. Position the antenna away from battery packs, metal shielding cans, and switching power supplies. No soldering is required.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"padding: 15px; background: #fafafa; border-radius: 8px;\"\u003e\n      \u003cp style=\"font-weight: bold; margin-bottom: 6px;\"\u003eQ: What is the difference between the TX4G-PCB-6613 and TX4G-PCB-4410?\u003c\/p\u003e\n      \u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: Both antennas cover 4G\/LTE bands with 3.0 dBi gain and IPX-I connectors. The TX4G-PCB-6613 (66 × 13mm, 120mm cable) has a larger radiator that improves low-band (700–900MHz) efficiency for NB-IoT, LTE-M, and rural LTE deployments. The TX4G-PCB-4410 (44 × 10mm, 145mm cable) is more compact with a longer cable, suited for space-constrained enclosures where low-band performance is less critical. Choose based on your enclosure dimensions and target LTE band priorities.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/section\u003e\n\n\u003c\/div\u003e","brand":"cdsenet","offers":[{"title":"Default Title","offer_id":45206482485350,"sku":"tx4g-pcb-6613","price":0.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/9918\/9350\/files\/TX4G-PCB-6613-_1_800x800_v2.jpg?v=1773476450","url":"https:\/\/cdsenet.store\/products\/tx4g-pcb-6613-4g-lte-nb-iot-pcb-antenna-3-0dbi-66x13mm","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
