Kenable RF TV Aerial Lead Cable - Black

It signifies a cable designed to carry radio frequency (RF) signals, specifically for connecting TV aerials or satellite dishes to your television or set-top box. 'Male' connectors have a central pin that inserts into a female port.

The coupler allows you to connect two male RF cables together, effectively extending the length of your connection. It can also be used to connect a male cable directly to a female RF port on a device, although the cable itself has male connectors.

This cable uses standard RF coaxial connectors and is designed for 75-ohm impedance, making it suitable for both terrestrial aerials (like Freeview) and many satellite receiver connections, provided the connectors match.

75 ohms is the characteristic impedance of the coaxial cable. This is the standard impedance for most television and video transmission systems, ensuring optimal signal transfer and minimizing reflections.

While this cable is coaxial, it is specifically designed for TV/aerial RF signals. It is generally not suitable for broadband internet connections, which often use different types of cables (like Ethernet) or specific coaxial standards for cable modems.

The 5mm diameter suggests a reasonably robust cable that offers good protection to the internal conductors. However, like all cables, it should be handled with care to avoid damage, especially at the connector points.

Ensure both male connectors are fully seated in their respective ports. Check that the female-to-female coupler (if used) is securely attached. Verify that the cable is connected to the correct RF input/output ports on your devices. Inspect the cable for any visible damage. Try a different cable if possible to rule out a faulty cable.

Ensure you are using the correct type of connector (RF coaxial male). Check if there is any obstruction or damage to the threading on the connector or port. If using the coupler, ensure it is compatible with the cable connectors.

This can be caused by a loose connection or internal cable damage. Firmly re-seat both ends of the cable and the coupler. Avoid moving the cable unnecessarily. If the issue persists, the cable may need replacement.
