Product overview
The Kimpok AL1204 is an FM FPV video transmitter for RC drone image transmission. Its hardware combines PLL frequency control, selectable transmission power and a built-in power filter in a unit measuring 44 × 28.6 × 14.7mm and weighing 25.3g. Integration requires space for the transmitter, a suitable antenna connection and a DC 7-30V (2-8S) supply. The video input is specified at 1V±0.2Vp-p typical, while the SMA antenna interface is rated at 50 Ohms.
The transmitter provides 16 channels across two eight-channel bands within 1080-1360MHz, with PIT, 25mW, 200mW, 1W and 4W settings. A single RGB-lit button selects band, channel and power; IRC Tramp control and a DATA pin support flight controller setup. Installation must secure the unit while avoiding vibration and high temperatures. An antenna must be connected before operation to prevent possible damage, and excessive supply interference must be avoided despite the built-in filter. The operating temperature range is -10 °C to +70 °C.
