What is the first step to resolve cable TV interference caused by amateur radio transmissions?

• A. Change the frequency of your transmissions
• B. Ensure all TV feed line coaxial connectors are properly installed
• C. Reduce the power of your transmitter
• D. Disconnect the TV from the cable

Answer: (B)

To resolve cable TV interference caused by amateur radio transmissions, the first step is to ensure that all TV feed line coaxial connectors are properly installed. This is important because improperly connected or damaged connectors can lead to poor shielding and susceptibility to interference from nearby radio frequencies, including those from amateur radio transmissions. Properly installed connectors create a solid connection that minimizes losses and helps to maintain signal integrity, reducing the chance that amateur radio signals will infiltrate the TV system. When connectors are loose, corroded, or damaged, it can create a pathway for unintended signals to enter the cable system. By tightening and securing these connections, the overall system's immunity to interference can significantly improve, making it a practical first step for resolving the issue before considering other options like changing transmission frequency or adjusting power levels.
