An electric cable from the LNB, why?
He was playing electric guitar and I decided to adjust the cable from the LNB to my receiver satellite and had a mild electric shock. My left hand was on the guitar strings in time. I wonder what the reason is. Obviously, theres an electrical signal through the cable to the LNB, but why not get a shock when adjusting the LNB without the guitar? Also, does anyone know what there is tension in the cable from the LNB?
It is because of a difference in ground potential between your guitar and your satellite box, which is caused by an incorrect ground or missing. If you put a meter between the two grounds that can measure voltage. The cable from the LNB alone takes 13 at 18 Volts DC at a place of low pollution, not enough to give a jolt electric. Furthermore, only make landfall and both the center director. Since you are touching the chassis ground on both devices felt the difference of ground potential. If both devices were grounded, as with 3 teeth in one take 3 points, you should not feel anything.
