Product overview
The Kimpok AL4210 is an analog video transmitter for integrating an FPV video link into a drone. Its 32 preset channels cover 3700–4320 MHz, placing transmission away from the 5.8 GHz band. Five selectable output settings—PIT, 2.5 W, 5 W, 7 W and 10 W—provide a choice of transmission power. Long-distance flight and operation around obstacles are intended applications. The supplied configuration is a transmitter accessory kit.
The aluminum module measures 66 × 36 × 16 mm and weighs 37 g, defining its physical integration requirements within an airframe. It accepts 12–36 V DC and connects to an antenna through an SMA port. An aluminum heat sink and built-in cooling fan manage heat, with overheat and antenna-loss protection included. Tuning is available through a push button and IRC Tramp (Smart Audio), including in-flight adjustment. The kit contains one transmitter, one antenna and one cable.
