Overview

The TOXU TX-A19 is a multi-band external paddle antenna developed for compatible cellular routers, wireless gateways, customer-premises equipment, industrial terminals, monitoring devices, and other 50Ω wireless systems.

The antenna covers four specified frequency ranges: 698-960MHz, 1575-2700MHz, 3300-3800MHz, and 5000-6000MHz. This combination supports integration with equipment operating in selected cellular and wireless communication bands.

Its vertically polarized antenna structure provides 5dBi nominal gain and a VSWR of ≤1.9 under the specified test conditions. The slim 196mm housing is suitable for devices requiring an external direct-mount paddle antenna.

The rotatable structure allows the antenna body to be positioned according to the installation direction of the connected equipment. SMA, RP-SMA, and customized connector configurations are available according to the customer’s RF interface.

The TX-A19 must be evaluated against the exact operating bands of the connected modem, module, router, or gateway. The antenna should not be described as supporting every global 4G or 5G frequency because its coverage is limited to the frequency ranges stated in the specification.

Key Features

Specified Multi-Band Coverage

The antenna covers 698-960MHz, 1575-2700MHz, 3300-3800MHz, and 5000-6000MHz for integration with compatible cellular and wireless equipment.

5dBi Nominal Gain

The 5dBi nominal gain supports signal transmission and reception when the antenna is properly matched, oriented, and installed with compatible RF equipment.

Vertical Polarization

The vertically polarized design is suitable for routers, gateways, industrial terminals, and other wireless equipment using a compatible antenna orientation.

Rotatable Paddle Structure

The adjustable antenna joint allows the paddle body to be positioned according to the device installation direction and available surrounding space.

SMA and RP-SMA Connector Options

SMA and RP-SMA versions are available for different equipment interfaces. The exact connector must be confirmed before ordering because their center contacts are different.

Compact Direct-Mount Design

The 196mm antenna uses a direct-mounted RF connector, eliminating the need for an external coaxial cable in the standard configuration.

PCB Internal Antenna Structure

The molded paddle housing contains a PCB-based antenna structure designed for the specified operating frequency ranges.

Customized RF Configuration

Connector type, housing configuration, branding, packaging, and project-specific frequency tuning can be evaluated according to customer requirements.

Technical Specifications

The listed frequency ranges and electrical parameters should be verified with the customer’s actual module, device enclosure, installation position, and operating environment before volume production.

Dimension Drawing

The TX-A19 has an overall length of 196 ±2mm. The main paddle section is approximately 171 ±2mm long and 38.3 ±1mm wide, while the connector section has an indicated diameter of 13 ±1mm.

Dimensions are shown in millimeters. Please confirm the connector version and final mechanical drawing before product integration or enclosure design.

Applications

• 4G LTE Routers

• Compatible 5G Sub-6GHz Equipment

• Cellular Gateways

• Customer-Premises Equipment

• Industrial IoT Gateways

• Wireless Communication Terminals

• Remote-Monitoring Devices

• Smart-Home Gateways

• Industrial Control Equipment

• Wireless Modems

• Security and Surveillance Equipment

• Compatible Multi-Band RF Devices

Compatibility depends on whether the exact operating frequency of the connected equipment falls within the specified TX-A19 frequency ranges.

System Integration

The TX-A19 can be connected directly to compatible cellular routers, modems, gateways, industrial terminals, monitoring devices, and wireless communication equipment using a 50Ω SMA or RP-SMA antenna interface.

Before ordering, the customer must check the exact operating bands of the modem or wireless module. General product descriptions such as “4G” or “5G” are not sufficient for confirming compatibility because different countries, operators, and modules may use different frequency bands.

The connector must also be checked carefully. SMA and RP-SMA connectors can have similar external threads, but their center-contact structures differ. Customers should provide the equipment datasheet, connector model, or a clear interface photograph if the connector is uncertain.

For suitable wireless performance, the antenna should normally be positioned vertically and kept away from large metal surfaces, shielded structures, motors, power supplies, high-current circuits, and other strong electromagnetic interference sources.

Actual communication distance and signal quality depend on the wireless module, network coverage, output power, receiver sensitivity, antenna matching, installation orientation, equipment enclosure, surrounding obstacles, and RF environment.

For customized projects, customers should provide the operating frequency bands, modem or module model, connector type, device structure, installation position, available space, application environment, and estimated order quantity.

FAQ

Q: Is the TX-A19 a 4G and 5G antenna?

A: It can be used with compatible 4G LTE and selected 5G Sub-6GHz equipment when the equipment’s operating bands fall within 698-960MHz, 1575-2700MHz, 3300-3800MHz, or 5000-6000MHz.

Q: Does it support every global 4G and 5G band?

A: No. The antenna is limited to the frequency ranges stated in the specification. The exact modem bands must be checked before ordering.

Q: Does the 1575-2700MHz range mean this is a GNSS positioning antenna?

A: No. The TX-A19 is a passive external communication antenna and does not contain a GNSS receiver or positioning function. System compatibility must be evaluated according to the connected equipment.

Q: Is the listed gain 5dBi?

A: Yes. The specified nominal gain is 5dBi. Actual installed performance depends on frequency, matching, equipment structure, antenna orientation, and the surrounding environment.

Q: What is the difference between SMA and RP-SMA?

A: SMA and RP-SMA connectors use different center-contact arrangements. Please confirm the equipment interface rather than selecting the connector only by its external thread.

Q: Can the antenna be rotated?

A: Yes. The paddle body uses an adjustable structure for flexible antenna orientation after installation.

Q: Can the connector and housing be customized?

A: Yes. Connector type, housing configuration, color, branding, packaging, and RF requirements can be evaluated according to the project and order quantity.

Q: What information is required before ordering?

A: Please provide the required frequency bands, modem or module model, connector type, equipment application, installation position, available space, operating environment, and estimated order quantity.
