Product overview
The Kimpok Technology ALV3305AC is an analog video transmitter supplied as a component kit containing one VTX, one antenna and one cable. Its aluminum alloy housing incorporates a cooling fan, with overall dimensions of 50 × 36 × 16mm and a weight of 40.4g. Integration connections comprise an SMA antenna connector and a six-pin JST cable connector. The transmitter accepts 7–26V input and provides a 5V camera supply with current restricted to under 500mA. Microphone support is absent.
The transmitter offers 64 channels across eight bands within 3060–3500MHz. Channel, band and power settings share one button, while IRC supports data control, OSD configuration and Pit Mode. The output specification lists 2000mW/5000mW, although the button instructions identify the second level as 6000mW, leaving an unresolved power-rating conflict. A three-second delay precedes amplifier startup. Holding the button for five seconds enters P mode at 0dBm; another five-second hold exits it. Connect the antenna before power-up, retain the cooling fan and handle hot surfaces carefully.
