These days we are being subtly encouraged to buy shielded cable for everything, including home telephone extensions. Shielding must be better, right? But the received wisdom , if you search for it, is that using shielded cable which is not properly earthed is worse than using no shielding at all, supposedly because the foil and drain wire can act as an antenna if not earthed.
BT has a strict prohibition against touching their wires, and they have invented a type of Network Termination Equipment called the NTE5 termination box to allow consumers to wire their own extensions in a relatively foolproof manner. Has anyone ever seen an earth connection on the NTE5 faceplate? Has anyone even seen an earth connection on the older master Line Jack Units? Has anyone seen any instructions or advice on how to use shielded cable in conjunction with any of BT's termination boxes?
If they have, I would really like to know.
