This one was done very carefully and is documented herein with great instructions and pix. It does make this little project seem very complicated, which it turns out not to be at all!
I make mine similarly with some minor variances, partly the result of experimentation and partly just out of laziness. But the basic formula works very very well and is much better than just an R-C on both cable ends, or an R-C array on both ends, or an ungrounded Ti-shielded R-C on both ends.
In fact, I posted that I wired my ground into another R-C array (also Ti=shielded) that was built into a plug. Talk about overdoing it! LOL But that works really well for me.
For starters, the simplest way is to just do one major value of C and one of R and put each of these R-Cs on each cable end. This can be done with wirenuts before permanently soldering, so you can experiment more easily with R values (and these may be idiosyncratic, so worth trying). Next step is the 3 descending R-C pairs forming an array and use that on each cable end.
Then you go for the whole grounded Ti-shielded deal.
