Thanks for the info gents. I’ve been trying to source some shielded cable the last couple days, but run into the problem of either they sell in 500ft increments, or it is sold by the foot but the shipping charges are ridiculous. One website has the cable I wanted for around $25 for 30ft of 16/4 shielded cable, but then wanted to charge $32 for shipping. I’ll take a look at the website you suggested!
