Lead shielding


I have made myself a cable tidy which effectively boxes my loudspeaker cables from my 2 aerial cables, and a phono lead from my TV to my amp. The makeup of my room makes this unavoidable.

I designed it with a view to shielding the TV based cables and running a grounding wire to a rod in the garden. I considered the following:
1. run the cables via copper pipes - grounding the said pipe
2. line the respective 'box'/'run' with lead - ground that.

I thought about lead because I saw a roll in my workshop, and understood it to be an effecive shield

For a moment, I'll assume that you were actually trying to ask a serious question. Don't waste your time trying to construct a shield for your cables as you described. If you're actually experiencing interference from radio signals, the methods for eliminating that are well known and documented. There's too much to go into here, unless you can tell me the source of the RF interference and frequency of the source signal. Also, what component is being interfered with - your TV, your stereo system, or both? Knowing all the above, the first step would be to determine how the unwanted signal is getting into the component experiencing the interference - could be through the AC power line, antenna line, speaker cables, interconnects. Once that's been determined, then a proper solution can be found. Note that such problems are almost always the fault of the TV or audio equipment not exhibiting the proper rejection of signals that are outside the frequency range that they're designed to deal with. Solutions may involve modifying the audio gear, or installing an appropriate filter (or choke) on the leads that are carrying the signal into the equipment. Tell me more about what's going on and I can give you some specifics.
Joking aside. My amp has a wall socket next to it. Under the wall socket is both my TV aerial, and satellite aerial. my tv is placed between my speakers. My speakers run parallel to the the aerial leads, as well as the tv - to amp phono lead. The shape of my room makes this unavoidable.

I am convinced that this is a recipe for RFI problems entering my audio chain.
