DESCRIPTION
The licence exempt X7301 CCTV Video Link consists of a compact 500mW radio transmitter and a highly sensitive radio receiver. Real time colour and monochrome composite video signals are presented to a BNC connector on the transmitter. These are then passed over a 1.394GHz radio link to a pair of screw terminals on the receiver. A range of 1Km to 4Km is possible in free space. Serial, analogue or digital camera controls signals can be transmitted back to the video transmitter via a licence exempt 458MHz radio link if required. Both the receiver and transmitter are powered from a regulated 12 volt source at 500mA.

Connect the video cable to VIN and GND video terminals using 75 ohm coaxial cable with tail ends. Connect a regulated 12V power supply rated at greater than 0.5 amps to the power terminals ensuring the correct polarity. RECEIVER Connect the VID and GND video terminal to a monitor using 75 ohm coaxial cable with tail ends. Connect a regulated 12V power supply rated at greater then 0.5 amps to the power terminals ensuring the correct polarity. PROPAGATION With any radio system there are a number of factors which affect the system performance. These are:
- Transmitter output power
- Height of transmitter and receiver antenna
- Length and type of coaxial antenna feeder
- Topography between transmitter and receiver
- The weather
