What type of signal is typically used by an ENG truck to send video and audio to a TV station?

• A. RF signal
• B. Microwave signal
• C. Infrared signal
• D. Digital signal

Answer: (B)

An ENG (Electronic News Gathering) truck typically utilizes a microwave signal to transmit video and audio to a TV station. Microwave signals are advantageous for this type of operation due to their ability to travel over long distances and penetrate obstacles, allowing for reliable communication in urban environments where physical obstructions may be present. These signals facilitate real-time broadcasting, which is essential for news gathering and reporting. Microwave transmission is also effective in providing high-quality video and audio feeds, making it suitable for live broadcasts. The frequency ranges used for these signals can maintain quality while being robust enough to handle various environmental conditions. Other signal types, like RF signals, may also be used for different aspects of broadcasting but are not specifically typical in the context of an ENG truck's functionality for live video and audio transmission. Similarly, infrared signals are limited in range and are not suitable for broadcasting purposes because they require a direct line of sight. Lastly, while digital signals can be transmitted over various media, the best fit for the requirements of an ENG truck's operations is the microwave signal, given its direct usage in field deployments for news coverage.
