Running 240V And Coax Together

[malagabob]

If I run a cable supplying power and coax for a TV side by side say for 5 mtrs, would the current from the power cable interfere with the TV signal. TIA

No, that's exactly why the radio/TV cable is co-axial - the out braided layer protects the central core from spurious interference.

As bhg481 says the screening on the coaxial cable should protect the video/audio cables from mains interference.

The wall mounted TV in our bedroom has the mains cable together with the screened video and audio cables (line level) within mini-trunking over a distance of around 4 metres. The screened cables are claimed to be of good quality. While there appears no degradation of the video signal, there is a noticeable mains hum from the TV speakers.

I’m considering mounting a second run of mini-trunking to separate the mains cable from the screened audio cables in an attempt to solve the issue.
