Product overview
The Kimpok Technology ALV3307AC is an analog video transmitter operating across 3060–3500 MHz, with 64 channels arranged in eight bands. The supplied kit contains one transmitter, one antenna and one cable. Its physical construction combines an aluminum alloy housing with a built-in cooling fan. The transmitter measures 50 × 36 × 16 mm and weighs 40.4 g; mounting-hole dimensions are specified as “30.*44.5 mm.” Connections comprise an SMA antenna connector and a 6-pin JST cable connector.
Electrical integration requires a 7–26 V input, while the camera power output provides 5 V for a load under 500 mA maximum. Microphones are not supported. IRC data supports OSD configuration, and Pit Mode is available. A single button selects channels, bands and power: short presses change channels, a two-second hold opens band selection, and a four-second hold opens power selection. At startup, the transmitter waits three seconds before turning on its power amplifier.
The rated switchable output levels are 2000 mW and 7000 mW, although the button instructions identify the second level as 6000 mW. This leaves the high-power setting inconsistent between the rating and control instructions. Holding the button for five seconds enters P mode at 0 dBm; another five-second hold exits it. The antenna must be connected before power is applied, and the cooling fan must remain installed. The transmitter also carries a warning that hot surfaces can burn fingers.
