Question about A/V cable shielding

by hazmike / July 31, 2007 6:26 AM PDT

If I were to buy an unsheilded component video cable and wrap it with electrical tape if I notice interference, will this work?

I am not sure what the difference in shielded vs unshielded cables is, I thought it may just be more 'stuff' around the cable. If so this could save me a ton. Asthetically, this will be hiden with all my other wires so I dont care about the 'black tape' looking cable.

Some FYI on cables Component cables are shielded!!!!
The are made from 75ohm coaxial cable, this has center conductor and out "shield" around the center conductor.
"wrap it with electrical tape" Electrical tape is an insulator NOT a shield, You will only waste the tape doing thins and gain nothing. John

Simply put, shielding reduces the effect of electromagnetic field on your wire. Electrical tape does not block this interference. Most good quality A/V cables have shielding built in. The easiest fix is to keep A/V cables away from power cords. Other than that you could wrap aluminum foil around your cables as another quick & dirty fix.

Another question about the sheilding

So if I have a six foot component cable and only need to run two foot. Can I wrap it in a coil or will it interfere with itself?

Thanks for previous responses and future ones as well.
