To address cable TV interference from ham radio transmissions, ensuring that all TV coaxial connectors are installed properly is a critical first step. This is because loose or improperly connected connectors can lead to poor signal integrity and cause interference with other electronic devices, including cable TV.

When connectors are secure and installed correctly, they minimize the risk of signal leakage and ensure that the TV receives a cleaner, more stable signal. This can help reduce the potential for the ham radio’s RF emissions to couple into the TV's reception system.

If the connectors are in good condition and properly secured, more advanced steps like changing the frequency of transmission or installing a band-pass filter can be considered, but checking the physical connections is a fundamental troubleshooting step. Reducing power output is not necessarily a solution for interference; optimizing the installation of connectors and equipment is more effective in resolving interference issues.
