Product overview
The Kimpok Technology AL3304 is an analog video transmitter for FPV aircraft installations, including lightweight setups and group racing applications. Its aluminum alloy housing combines an aluminum heat sink with a built-in cooling fan, while overheat and antenna-loss protection provide circuit safeguards. The module measures 44 × 28.6 × 14.7mm and weighs 25.3g, defining the space and mass required for integration. The supplied configuration comprises one transmitter, one antenna and connecting cables; it is a component kit for installation in an aircraft.
Electrical integration requires a 7–36V DC supply, with compatibility stated for 2–8S LiPo batteries. An SMA connector provides the antenna interface, and selectable output settings are PIT, 25mW, 200mW, 1W and 4W. Push-button tuning and IRC Tramp (Smart Audio) support channel and power adjustment. The 3.3GHz operating specifications contain an unresolved mismatch: 3170–3470MHz and 16 channels are specified alongside 3060–3550MHz and 64 preset channels. The 4W setting is positioned for longer-range video with balanced power draw.
