Overview

The TOXU TX-A190 is a compact 5.8GHz mushroom antenna designed for compatible FPV video transmitters, video receivers, UAV image-transmission equipment, and other 5.8GHz wireless devices.

The available product specification states 3dBi gain, vertical linear polarization, VSWR of ≤2.0, 50Ω impedance, and optional SMA male or RP-SMA male connector configurations.

Its flexible coaxial section allows the antenna position to be adjusted according to the installation space of the UAV, FPV transmitter, receiver, or ground-station equipment.

The TX-A190 is a single-band 5.8GHz antenna. It should not be described as a 2.4GHz and 5.8GHz dual-band antenna unless an additional verified specification confirms 2.4GHz operation.

Final video-link performance depends on the exact operating frequency, transmitter power, receiver sensitivity, antenna orientation, mating connector, installation position, surrounding obstacles, electromagnetic interference, and operating environment.

Key Features

5.8GHz FPV Frequency

Designed for compatible FPV video-transmission and wireless communication equipment operating in the 5.8GHz frequency band.

3dBi Specified Gain

The available product information specifies 3dBi antenna gain for compatible short-range UAV and FPV wireless links.

Vertical Linear Polarization

The antenna uses vertical linear polarization and should be paired with equipment using a compatible polarization configuration.

Compact Mushroom Structure

The compact antenna head is suitable for installation on compatible FPV transmitters, receivers, UAV platforms, and portable wireless equipment.

Flexible Cable Section

The flexible coaxial section supports convenient antenna positioning according to the equipment layout and available installation space.

SMA and RP-SMA Options

SMA male or RP-SMA male connector configurations can be selected according to the mating interface of the FPV transmitter or receiver.

50Ω RF Compatibility

The antenna uses a standard 50Ω impedance for integration with compatible RF video-transmission and wireless communication equipment.

Project Customization Support

Connector configuration, cable length, antenna label, housing color, and packaging can be evaluated according to project requirements and order quantity.

Technical Specifications

Applications

• FPV UAV Video-Transmission Systems

• FPV Video Transmitters

• FPV Video Receivers

• Racing Drones and Multirotor UAVs

• UAV Aerial-Photography Equipment

• 5.8GHz Wireless Video Links

• FPV Ground-Station Equipment

• Remote Video-Monitoring Systems

• Compatible 5.8GHz Wireless Devices

System Integration

The TX-A190 can be integrated into a compatible FPV image-transmission system using one of the following configurations:

UAV Camera → 5.8GHz Video Transmitter → TX-A190 Antenna

TX-A190 Antenna → 5.8GHz Video Receiver → FPV Display or Ground Station

Before ordering, confirm that the connected transmitter or receiver operates at 5.8GHz and uses a compatible 50Ω RF interface.

SMA and RP-SMA connectors are physically similar but use different center-contact structures. The exact connector type and gender must therefore be confirmed before production.

Because the TX-A190 uses vertical linear polarization, the antenna connected to the opposite end of the wireless link should use a compatible polarization configuration. Pairing it with a circularly polarized antenna may introduce additional polarization loss.

Keep the antenna away from carbon-fiber plates, batteries, motors, high-current power cables, metal structures, and other components that may block or interfere with the RF signal.

Do not operate the FPV transmitter without a correctly connected antenna. Running a transmitter without a suitable antenna may cause reflected power and damage the RF output stage.

Sample testing with the actual transmitter, receiver, connector, operating channel, installation position, UAV structure, and flight environment is recommended before volume ordering.

FAQ

Q: Is the TX-A190 a 2.4GHz and 5.8GHz dual-band antenna?

A: No. The currently available specification only confirms 5.8GHz operation. It should not be promoted as a dual-band antenna without additional verified technical data.

Q: What is the antenna gain?

A: The available product information specifies 3dBi gain.

Q: Is this an RHCP or LHCP FPV antenna?

A: Neither is confirmed. The current specification states vertical linear polarization, not right-hand or left-hand circular polarization.

Q: Can it be used for an FPV video transmitter?

A: Yes, provided that the transmitter operates at 5.8GHz and uses a compatible 50Ω SMA or RP-SMA interface.

Q: Can it be used on an FPV receiver?

A: Yes. It can be connected to a compatible 5.8GHz FPV receiver after confirming the connector and polarization requirements.

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

A: They use different center-contact structures even though their outer threads may appear similar. The equipment interface must be checked before ordering.

Q: Is the antenna omnidirectional?

A: The current information does not include a radiation-pattern chart or confirmed radiation-type specification. Final coverage should be verified through sample testing.

Q: Can the antenna guarantee a specific FPV transmission distance?

A: No. Transmission distance depends on transmitter power, receiver sensitivity, operating channel, antenna installation, obstacles, interference, polarization matching, and the surrounding environment.

Q: Can the connector and cable length be customized?

A: Yes. Connector configuration, cable length, label, housing color, and packaging can be evaluated according to project requirements and order quantity.
