KP-500TX4W is a -new wireless video transmission device, which adopts FM modulation mode and -new frequency, avoiding the 1.2Ghz/1.5Ghz/2.4Ghz wireless transmission that has been used more in the same range, avoiding the same frequency interference, and is more suitable for use in complex environments.The receiver sensitivity is -85dBm, and the transmitted image is clear and stable. With a ground high-gain antenna, it can transmit 2-3km in the open area of the city, and about 40km in the air-to-ground LOS (the transmission distance is different in different environments, and the specific transmission distance depends on the actual working environment).The transmitter is exquisitely crafted, made of special metal, and also has a high-speed fan, which is more conducive to heat dissipation and more suitable for long-term work.The signal input adopts a universal AV interface, which can be easily compatible with all conventional AV interfaces such as cameras, , , etc.KP-500TX4W is not only a professional wireless CCTV transmitter and receiver for CCTV security projects, but also can be used for video transmission of FPV systems, drones, model aircraft/helicopters, unmanned equipment vehicles, etc.500Mhz 4W VTX Specification:Model number:KP-500TX4WVoltage:DC 12VCurrent:700mAModulation:FMFrequency:500MhzChannels:8 channelsTransmit Power:4wattVideo Output:1 -p(FM)Temperature:-10~+50Antenna port:SMATransmitter Weight:60gDimensions:60x42x19mmDue to different product batches, the appearance of some parts may be different, which will not affect the use.Type:VTXColour:As ShownMaterial:Aluminum AlloyPackage Contents:1 * Transmitter KitOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
