Date: June 24, 2026
Category: Product Launches / UAV Technology
As the demand for Beyond Visual Line of Sight (BVLOS) operations, industrial mapping, and extreme long-range FPV missions continues to skyrocket, video link reliability remains the ultimate challenge for UAV pilots. Today, AirLink officially announces the release of its flagship video transmitter—the AirLink AL3304 3.3GHz 4W VTX—a heavy-duty powerhouse engineered to redefine the limits of wireless video transmission.
Operating on the Clean 3.3GHz BandMost commercial and hobbyist drones crowd the 2.4GHz and 5.8GHz spectrums, leading to severe signal degradation in urban or high-interference zones. The AL3304 utilizes the dedicated 3.3GHz frequency band, providing a much cleaner RF environment. Combined with its massive 4W (36dBm) maximum output power, this VTX delivers unparalleled penetration, easily cutting through dense foliage, complex terrain, and urban concrete obstacles that kill standard video links.
Key Technical Specifications at a Glance:Output Power: Adjustable 5 levels (PIT / 25mW / 200mW / 1W / 4W)Input Voltage: DC 7-30V (Direct 2S to 8S LiPo battery compatibility)Control Protocols: Supports physical single-button setup (with RGB status LEDs) and remote flight controller telemetry via the DATA pin (IRC Tramp).Onboard Filtering: Built-in heavy-duty power filter suppresses ESC and motor electrical noise, delivering a high Signal-to-Noise Ratio (SNR) for crisp analog feeds.
