After connecting this cord, the image disturbance was completely gone. So the cable has its purpose to eliminate the image distortion, fully met.
The cable delivered me from Marketplace Dealers Electronics Point is exactly the illustration shown here. It bears an inscription "SAT / BK COAXIAL DOUBLE SHIELDED-CE-CLASS-A" is therefore probably not 5 times but only 2-way shielded, which is why I deducted a star because of incorrect product description (see. My customer photo) ,
