Kimpok AirLink AL3304 3.3G 4W High-Power VTX with Cooling Fan

Product Overview

The AirLink AL3304 is a premium, high-performance wireless video transmitter (VTX) engineered specifically for long-range FPV drones and fixed-wing RC aircraft. Operating on the clean 3.3GHz frequency band, it delivers an impressive 4W of RF output power with flexible multi-level adjustments (PIT/25mW/200mW/1W/4W) to adapt to any flight environment. Weighing just 25.3g and equipped with an active dual-cooling system, the AL3304 is the ultimate powerhouse built for extreme distance, endurance, and reliability.

Key Features

Massive 4W Output with Smart Power ScalingFeatures 5 adjustable power levels (PIT/25mW/200mW/1W/4W), allowing you to effortlessly switch from safe close-range bench testing to extreme long-range missions.

Zero Frequency DriftUtilizes a customized digital PLL circuit with chip-level integration to guarantee absolute signal locking and frequency stability, eliminating video fading caused by thermal drift.

Active Dual-Cooling SystemEngineered with a premium three-layer aluminum alloy heatsink housing and an integrated high-volume centrifugal fan, ensuring sustained 4W maximum power output without overheating.

Dual-Mode Smart ConfigurationSupports instant, onboard physical button configuration as well as remote flight controller setup via the telemetry (IRC Tramp protocol).

Core Advantages
Unmatched Range and Penetration
The robust 4W output and optimized Power Amplifier (PA) deliver ultra-stable, crisp video feeds, easily cutting through complex terrain, foliage, and high-interference environments.

2S-8S Wide Voltage Input
Supports a broad DC 7-30V input range, allowing you to power the VTX directly from your aircraft's main flight battery without the need for bulky external BECs.

Built-in Power Filter
Integrated active power filtering cleans up electrical noise from the motors and ESCs, achieving a high Signal-to-Noise Ratio (SNR) for interference-free, crystal-clear imaging.

Lightweight Heavyweight Performance
Despite its rugged, crash-resistant all-metal enclosure and built-in fan, it weighs only 25.3g, maximizing your aircraft's flight time and payload capacity.

Target Applications

• Long-Range Missions: Ideal for ultra-long-distance FPV drones, quadcopters, and fixed-wing UAVs.

• Complex Environments: Perfect for BVLOS (Beyond Visual Line of Sight) flights through dense or high-RF interference zones.

• Industrial and Enterprise: Trusted for professional drone mapping, search and rescue (SAR), and industrial inspection where video link failure is not an option.
