FAQ
What is the AKK Ultra Long Range 3W VTX?
It is an analog FPV video transmitter supporting 4.9GHz and 5.8GHz operation, 80 selectable channels, SmartAudio and output power up to 3000mW.
Which frequency bands and channels does it support?
The VTX supports 4.9GHz and 5.8GHz frequency bands with a total of 80 selectable channels. The receiving equipment must support the selected frequency and channel.
What output power levels are available?
The available selectable output levels are 250mW, 1000mW, 2000mW and 3000mW.
What input voltage does the VTX support?
The supported input voltage is 8–28V DC. Always verify the wiring polarity and system voltage before applying power.
Does the VTX support SmartAudio?
Yes. SmartAudio allows a compatible flight controller to control the VTX channel and output power when the connection and firmware settings are configured correctly.
Why does the VTX include a cooling fan?
High-power video transmitters generate significant heat. The integrated fan and aluminum heat sink improve airflow and heat dissipation during operation.
Does the VTX have a built-in microphone?
Yes. The integrated microphone can provide audio transmission when used with compatible analog FPV receiving equipment.
What are the dimensions of the VTX?
The board measures approximately 36 × 36mm and uses 3mm mounting holes.
Can the VTX achieve a 20km transmission distance?
The product is designed for ultra-long-range FPV applications, but actual range depends on antennas, receiver sensitivity, installation, terrain, interference, line of sight and permitted transmission power. A specific distance cannot be guaranteed in every operating environment.
Must an antenna be connected before powering the VTX?
Yes. Always connect a compatible antenna before applying power. Operating a high-power VTX without a suitable antenna can damage the transmitter.
