Product overview
The Kimpok AL4205 is a video transmission component for integration into FPV aircraft, with applications spanning long-range flying, surveying and mapping, and UAV inspection. Its operating range is 3700MHz-4320MHz, presented as 3.7GHz-4.3GHz, with 32 selectable channels. Output settings comprise PIT, 25mW, 2W and 5W, with 5W as the maximum RF output. Selectable channels and power settings provide configuration options for different transmission requirements.
The aluminum unit measures 44*28.6*14.7 mm and weighs 25.3g with its built-in cooling fan, giving aircraft integrators a defined component envelope and installed mass. Power input is 7-36V DC, with compatibility specified for 2S~8S LiPo batteries. The configuration is a compact FPV video transmitter with integrated cooling for use aboard a drone. It is a component rather than a complete flight platform or an airframe kit; its stated applications include woodland, mountain and cross-country missions.
