AKK Alpha 4 5.8GHz 4W 80CH VTX

The AKK Alpha 4 is a heavy-duty analog video transmitter engineered for extreme long-range FPV, high-altitude fixed-wing platforms, and heavy-lift UAVs pushing the limits of 5.8GHz video links. Delivering a massive 4000mW of maximum output power, this VTX is designed to punch through dense foliage, structures, and atmospheric interference to maintain a solid signal lock at extended distances where standard 1W or 2W transmitters drop out.

Key features

• Selectable output power scaling up to a staggering 4000mW for extreme long-range penetration.

• Expanded 80-channel frequency support to help you hunt down clean bands in congested RF environments.

• High-mass integrated aluminium heatsink designed to dissipate the heavy thermal load of 4W transmission.

• SmartAudio support allows remote channel, band, and power adjustments directly through your flight controller or radio.

• Wide voltage input range handles direct battery voltage from large multirotors and fixed-wing builds.

Specifications

• Frequency band: 5.8GHz analog

• Channels: 80CH

• Output power: Up to 4000 mW (4W)

• Input voltage: 7-36V (2-8S LiPo)

• Control protocol: SmartAudio

Due to the massive thermal output generated at 4000mW, you must mount this VTX where it will receive continuous, direct airflow during flight. Always ensure a high-quality, perfectly seated antenna is connected before applying power to prevent instant thermal damage to the amplifier.
