Overview

The TOXU TX-A122 is an 800–860MHz flexible rubber duck antenna developed for ISM, LPWAN, telemetry, remote-control, and industrial wireless communication equipment.

The antenna operates across the 800–860MHz frequency range and provides 2dBi gain with a 50Ω impedance. Its compact 130mm whip structure is suitable for direct installation on compatible wireless terminals, radio equipment, data transmission units, and industrial control devices.

The TX-A122 is available with SMA or BNC connector configurations. The operating frequency, RF connector, antenna length, and mechanical structure can also be customized according to the customer’s communication module, enclosure, and installation requirements.

Key Features

800–860MHz Sub-GHz Operation

Designed for compatible ISM, LPWAN, telemetry, and industrial wireless systems operating within the 800–860MHz frequency range.

2dBi Antenna Gain

Provides 2dBi gain for balanced signal transmission and reception in compatible sub-GHz wireless communication applications.

Flexible Rubber Duck Structure

System Integration

The TX-A122 can be connected directly to compatible wireless modules, radios, gateways, telemetry units, and industrial communication terminals equipped with a 50Ω SMA or BNC RF interface.

The connected communication equipment must operate within the antenna’s specified 800–860MHz frequency range. This product should not automatically be treated as an 868MHz, 915MHz, cellular, Wi-Fi, or GNSS antenna unless a separately tuned version has been confirmed.

Actual system performance depends on the operating frequency, connector configuration, enclosure material, antenna orientation, installation position, RF matching, transmitter power, receiver sensitivity, and surrounding environment.

For improved performance, the antenna should be installed vertically and positioned away from large metal obstructions, high-current circuits, and strong electromagnetic interference sources.

Before ordering, customers should confirm the exact operating frequency, communication module or radio model, connector series, connector gender, equipment structure, and expected order quantity.

FAQ

Q: What frequency range does the TX-A122 support?

A: The standard TX-A122 operates from 800MHz to 860MHz, with 830MHz used as its nominal frequency.

Q: Is this a LoRa antenna?

A: It can be used with compatible LoRa or LPWAN equipment only when the equipment operates within the specified 800–860MHz range. Compatibility should be confirmed according to the exact regional frequency and module.

Q: Can this antenna be used at 868MHz or 915MHz?

A: The standard version is specified for 800–860MHz. A separately tuned antenna should be selected or developed for 868MHz or 915MHz applications.

Q: Is the TX-A122 an active or passive antenna?

A: It is a passive whip antenna and does not require a separate DC power supply.

Q: Which connectors are available?

A: SMA and BNC connector configurations are available. The exact connector series, gender, and polarity should be confirmed before ordering.

Q: Can the operating frequency and connector be customized?

A: Yes. TOXU can customize the frequency, connector, antenna length, and mechanical structure according to the customer’s device and project requirements.

Q: What information should be provided before ordering?

A: Please provide the exact operating frequency, communication module or radio model, connector type and gender, installation environment, required quantity, and any mechanical restrictions.
