small cable, big impact!

I rented me short, a cable digital receiver on "Tele Columbus". Had he connected and had focused, migrated, strips (beams) on my "LCD TVs". Had all antennas u. Scartkabel hergetauscht back and. the image was not getting any better. But then had to take advantage of the emergency service of "Tele Columbus". As has it turned out:. LCD Fernsher & Digital Box are grounded (Hence the disturbance) I was advised to join a "sheath current filter" to the cable socket and then to connect to the receiver via the antenna cable..

This "ground breaker" were all my problems go away !! Now have a super picture.

Ps: Warning !!!!!! Had bought the first cable for "Digital Cable", which should have these "Mantelstromfilter" already integrated. This cable was expensive and did not have any effect as this what I had before. (Triple Shielded)
