Overview

The TOXU TX-A133 is a compact 2.4GHz WLAN monopole antenna designed for Wi-Fi, IoT, wireless gateway, router, monitoring, and embedded communication equipment.

It uses a miniature rubber antenna cover with a stated length of 21mm, helping reduce the external space required by compact wireless devices.

The antenna features omnidirectional radiation and 2.1dBi nominal gain, supporting wireless signal transmission and reception around the antenna in compatible installation environments.

Its threaded through-hole mounting structure allows the antenna to be secured to a suitable equipment enclosure or mounting panel using the matching nut and washer.

A coaxial pigtail cable connects the external antenna element to the RF interface inside the equipment, making the TX-A133 suitable for devices where the wireless module or PCB is separated from the antenna mounting position.

Available cable options include RG178, RG316, 1.13mm, and 0.81mm coaxial cable. Connector options include U.FL-compatible miniature connectors, MURATA MXTK GSC, MMCX, MCX, SMA, and other configurations.

The final connector, cable type, cable length, mounting thread, and mechanical dimensions must be confirmed according to the actual device structure before ordering.

Key Features

2.4GHz WLAN Frequency Band

Designed for compatible wireless communication equipment operating in the 2.4GHz WLAN frequency band.

Compact 21mm Antenna Cover

The miniature rubber antenna cover has a stated length of 21mm, supporting integration into space-constrained wireless devices.

Omnidirectional Radiation

The monopole antenna structure provides omnidirectional radiation for signal transmission and reception around the antenna in suitable installation environments.

2.1dBi Nominal Gain

The available product information specifies a nominal gain of 2.1dBi. Final installed performance should be verified with the actual enclosure and device.

Through-Hole Screw Mount

The threaded base, fixing nut, and washer support secure installation through a suitable hole in an equipment enclosure or mounting panel.

Coaxial Pigtail Connection

The integrated pigtail cable allows the antenna to connect to a wireless module or PCB located inside the equipment.

Multiple Cable Options

RG178, RG316, 1.13mm, 0.81mm, and other suitable coaxial cables can be evaluated according to space, flexibility, attenuation, and routing requirements.

Custom Connector Support

U.FL-compatible miniature connectors, MURATA MXTK GSC, MMCX, MCX, SMA, and other RF connector configurations can be evaluated for volume-order projects.

Technical Specifications

Note: The available product information confirms only the 2.4GHz WLAN frequency band and does not provide a precise numerical frequency range. The stated 21mm dimension refers to the antenna cover length rather than the overall assembly size. Final cable type, cable length, connector, mounting thread, installation-hole diameter, and complete mechanical dimensions should be confirmed before ordering.

Applications

• 2.4GHz Wi-Fi Routers and Access Points

• IoT Gateways and Wireless Terminals

• Smart Home and Building-Automation Equipment

• Industrial Wireless Controllers

• Remote Monitoring Devices

• Wireless Sensors and Data Collection Equipment

• Embedded WLAN Devices

• Security and Monitoring Equipment

• Compact Communication Terminals

System Integration

The TX-A133 can be integrated into compatible 2.4GHz wireless equipment using the following connection:

TX-A133 Antenna → Coaxial Pigtail Cable → Wi-Fi Module / WLAN PCB / Wireless Gateway

Before integration, confirm that the connected RF module operates within the 2.4GHz WLAN band and uses a compatible 50Ω RF interface.

Install the threaded antenna base through a suitable hole in the equipment enclosure and secure it using the matching nut and washer. The required installation-hole diameter, thread specification, and compatible panel thickness should be confirmed before enclosure production.

Select the coaxial cable according to the available internal space, required flexibility, routing distance, and acceptable signal loss. Longer or thinner cables may introduce additional insertion loss.

Avoid routing the cable close to power converters, motors, high-current wiring, digital clocks, or other potential interference sources. Excessive bending, pulling, and compression of miniature coaxial cables should also be avoided.

The surrounding enclosure, PCB, metal components, installation position, cable routing, and device ground structure may affect antenna impedance, efficiency, gain, and radiation performance.

Sample testing with the actual wireless module, enclosure, installation position, cable configuration, and target operating environment is recommended before volume production.

FAQ

Q: What frequency band does the TX-A133 support?

A: It is designed for compatible wireless equipment operating in the 2.4GHz WLAN frequency band.

Q: Does it support 5GHz or 5.8GHz Wi-Fi?

A: The current product information confirms only the 2.4GHz WLAN band. Support for 5GHz or 5.8GHz should not be assumed.

Q: Is the TX-A133 an omnidirectional antenna?

A: Yes. The available product information identifies it as an omnidirectional monopole antenna.

Q: What does the 21mm dimension represent?

A: It refers to the stated length of the rubber antenna cover, not the complete antenna assembly or overall installed height.

Q: How is the antenna installed?

A: It uses a threaded through-hole mounting structure with a fixing nut and washer. The mounting-hole diameter and thread specification should be confirmed before integration.

Q: Which coaxial cables are available?

A: Available options include RG178, RG316, 1.13mm, and 0.81mm coaxial cable. The final cable should be selected according to the device structure and RF requirements.

Q: Which connectors can be supplied?

A: U.FL-compatible miniature connectors, MURATA MXTK GSC, MMCX, MCX, SMA, and other configurations can be evaluated.

Q: Can the cable length be customized?

A: Yes. Cable length can be evaluated according to the internal routing distance, connector location, device structure, and order quantity.

Q: Can 2.1dBi gain be guaranteed after installation?

A: The stated 2.1dBi value is nominal. Actual performance depends on the frequency, enclosure, ground structure, mounting position, cable loss, and surrounding components.

Q: Is sample testing recommended?

A: Yes. Testing with the actual wireless module, enclosure, cable routing, and installation position is recommended before volume production.
