Product overview
The Kimpok Technology ALV3304AC provides video transmission for FPV racing quadcopter integration. Its 50 × 36 × 16mm body weighs 40.4g and incorporates a cooling fan, an SMA antenna connection and a six-pin JST cable connection. The mounting-hole dimension is given as 30.*44.5mm. The supplied configuration comprises one transmitter, one cable and one antenna. Integration requires a 7–26V input; a 5V camera supply is available with a stated maximum current below 500mA. Microphone support is absent.
Channel selection covers 64 channels across eight bands within 3060–3500MHz. A single button handles channel, band and power changes, while IRC supports OSD configuration and Pit Mode access. The amplifier starts after a three-second delay. Output is specified as 2000/4000mW, although the button instructions assign 6000mW to the second level, leaving a material power-setting inconsistency. The transmitter carries a 10km range designation. Its antenna must be connected before power-on, the cooling fan must remain fitted, and hot surfaces require care.
