Camera VHF Video Transmitter

This is a simple video transmitter capable of transmitting signals up to 50 meters. It can be connected to a camera or other video sources, allowing viewing on a VHF channel analog TV. The transmitter operates on a supply voltage of 9V, which can be provided by a battery. The transistor component utilized in this video transmitter is the BC548, although alternative transistor types may also be employed.

This video transmitter circuit is designed for short-range transmission of analog video signals. The core function of the transmitter is to modulate the video signal from the source, such as a camera, onto a VHF frequency suitable for transmission. The BC548 transistor serves as the primary active component in this circuit, functioning as an amplifier and oscillator to generate the necessary RF signal for VHF transmission.

The circuit typically includes a power supply section, which in this case is a 9V battery, ensuring that the transmitter operates efficiently without the need for an external power source. The input from the video source is fed into the base of the BC548 transistor, where it is amplified. The output from the collector of the transistor is then coupled to a tuned circuit, which is essential for selecting the desired transmission frequency.

An LC circuit, consisting of an inductor and capacitor, is often used to create a resonant frequency that matches the VHF channel being used. This ensures that the transmitted signal is clean and occupies the correct bandwidth. The output signal can then be broadcasted via an antenna, which is typically a simple dipole or a monopole design that is tuned to the operating frequency.

To enhance the performance of the transmitter, it may be beneficial to include additional components such as filtering capacitors to reduce noise and improve signal quality. Proper grounding and shielding techniques should also be implemented to minimize interference and ensure stable operation over the specified range of 50 meters.

Overall, this video transmitter circuit is a straightforward yet effective solution for transmitting video signals wirelessly, making it suitable for various applications, including surveillance, remote monitoring, and hobbyist projects.This is a simple video transmitter that can transmit as far as 50 meters.
