Audio cable shielding - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2010 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

NOTICE: The original RF Cafe Forum is available again for reading, and the new RF Cafe Blog is an active board.

Hi everyone, quick question from a total novice....
I don't want to replace a 'lot' of expensive audio cable to shield it. Can I just run it through copper pipe to shield it from RF and other interference?

Thanks in advance

Greetings Lostcause:

Running your cable through copper pipe and grounding one end will shield everything inside from outside interference. However, if cables that were not closely bundled end up being so when moved into the pipe, you could end up with cross-talk interference that either did not exist or was unnoticeable before.

...just a caveat

Howdy Lostcause!

If you haven't already routed the cables through the pipe... something I have had a lot of love with it using earthing braid. You get it at most harware stores (here anyway) and it's pretty cheap. You just open up the braid aand it becomes a hollow tube that you can thread the cable through. it works like a ninja for RF and it has the advantage of being flexible. If you feel like a lot of effort, you can also strip the braded part off of old coax (RG223 double braid works well because you get two different sizes.) which is much thinner than the braid o your can stuff a few shileded cables down one braid.

Hope that helps! :)

Like that idea, I have a ton of braid and never even thought of it as hollow......Cool!

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
