Product overview
The Kimpok 1.2G 4.5W is an analog video transmission component for drone FPV installations, with applications spanning racing, aerial imaging, inspection and mapping. Its radio architecture combines FM modulation with PLL frequency control across 1080 ~ 1360 MHz, offering 16 channels in bands A/B. Selectable output modes cover PIT, 25mW, 200mW, 2W and 4.5W. IRC control supports remote power and channel changes, together with OSD parameter adjustment, allowing these settings to be managed within an integrated FPV installation.
The transmitter measures 48.5 × 35 × 21.5 mm and weighs approximately 38.8g, defining its installation space and mass contribution. Its physical configuration incorporates an aluminum heat sink and cooling fan, with built-in temperature control for overheating protection. Electrical integration requires DC 7V ~ 30V input; the unit also provides DC 5V output. Video input is CVBS at 1Vp-p ±0.2V, and the antenna connection is SMA with 50-ohm impedance. Its operating temperature range is -10°C to +60°C.
