Detailed Technical Specifications

Installation and Usage Guide

This Tablet 4G Data Antenna is designed for internal installation in compatible tablet devices. It can be used in device manufacturing, maintenance, and antenna replacement projects. Installation should be carried out by personnel familiar with tablet disassembly and RF connector handling. The specific installation steps are as follows:

1. Disassembly and Cleaning: Turn off the tablet device, remove the back cover, and clean dust and debris from the internal installation area. Ensure the mounting surface is flat, clean, and free of protrusions or obstructions.

2. Positioning and Attachment: Remove the high-temperature-resistant adhesive protective film from the back of the antenna. Align it precisely with the reserved antenna position inside the tablet, placing it on a clear area of the device body that is unobstructed by metal. Gently press for 3 to 5 seconds to ensure the antenna adheres securely, without looseness or lifting edges.

3. Interface Connection: Align the IPEX connector at the end of the antenna with the RF socket on the tablet motherboard, then press down vertically until it is securely connected. Ensure good contact with no loose connections or poor contact. This connection arrangement is relevant when selecting an IPEX 4G LTE Antenna for a compatible tablet RF interface.

4. Organize cable routing: Neatly arrange the antenna cables to avoid excessive pulling, bending, or compression, and keep them away from heat-generating areas such as the battery and motherboard to prevent long-term aging and damage.

5. Installation test: Reattach the tablet back cover, secure the fixing screws, power on the device, enable 4G network, test internet speed and signal strength, and confirm there are no signal anomalies or disconnection issues before normal use.

Product Selection Guide

When selecting a Tablet 4G LTE Antenna, common considerations include frequency compatibility, installation space, connector type, and RF performance. The following points can help determine whether the proposed antenna is suitable for a particular tablet project.

• Check frequency band compatibility: Prioritize antennas that cover the required frequency bands. For domestic devices, verify compatibility with the intended carrier bands; for export devices, confirm support for the frequency bands used in the target market. Missing bands may affect signal reception and data performance.

• Check the material and craftsmanship: A flexible FPC 4G Antenna can accommodate internal installation requirements where a thin, flexible substrate is needed. Review the substrate, conductive element, and insulating coating to determine whether the design is suitable for the intended installation environment.

• Check actual test parameters: Review available test reports and measurement data. Key parameters include gain, SWR, and impedance. Confirm that the measured performance meets the requirements of the target device and operating bands.

• Check compatibility dimensions: Select the appropriate antenna dimensions according to the tablet's internal space. For ultra-slim devices, consider the 0.15mm-thick design and verify the available mounting area, cable route, and clearance. Custom non-standard sizes may be discussed to address installation constraints.

• Check the RF connector: The IPEX/U.FL connector should match the RF socket on the tablet motherboard. Confirm the connector generation, cable length, and connection arrangement before ordering. An Internal LTE Antenna for Tablet projects may require a different connector or cable configuration depending on the device design.

• Check customization and supply capability: For projects with special dimensions, cable lengths, connector requirements, or frequency configurations, a Custom Tablet Antenna can be evaluated according to the device specifications. Confirm samples, testing requirements, production quantities, and lead times before mass production.

• Check the manufacturer's capabilities: Consider the manufacturer's experience, product testing, quality control, customization options, and after-sales support when selecting a long-term antenna supplier.

FAQ

Q1: Does this Tablet 4G Data Antenna support overseas 4G networks?

A: The antenna supports the frequency bands listed in the technical specifications. For export equipment, compare these bands with the LTE bands used in the target country and the tablet's modem requirements. Additional frequency configurations may be discussed if the standard specifications do not cover the required bands.

Q2: Can the antenna be customized in terms of size, connector type, and cable length?

A: Yes. Customization options may include antenna dimensions, cable length, connector type, and frequency configuration according to the equipment's internal structure. For a Custom Tablet Antenna project, provide the available installation space, required LTE bands, RF connector details, and target application so compatibility can be evaluated.

Q3: How long is the product warranty? How are quality issues handled?

A: The product comes with a 1-year warranty and lifetime maintenance service. For quality issues not caused by human damage, the stated service policy provides free replacements or reshipments, along with technical support to address usage problems. Confirm the applicable terms when placing an order.

Q4: Will frequent bending damage a flexible antenna?

A: The product uses a flexible FPC substrate designed for internal installation. Avoid sharp folds, repeated excessive bending, or pressure on the radiating element and feeder cable. The installation should follow the antenna's mechanical requirements to help maintain its structure and RF performance.

Q5: What is the minimum order quantity? Can mixed batches be supplied?

A: Standard in-stock products are stated to have no minimum order quantity, with small mixed batches and occasional purchases supported. Large orders may qualify for tiered pricing. Confirm current stock, customization requirements, and production lead times before ordering.

Q6: What connector does the antenna use?

A: The standard interface is an IPEX/U.FL universal connector, with customizable terminal options. The connector should be checked against the tablet motherboard's RF socket. For an IPEX 4G LTE Antenna requirement, confirm the connector generation and cable length before production.
