[QUOTE="chris229, post: 85274, member: 542614"] it NOT a shield --------- you must study some facts about EMI----------- the purpose of UTP's is -------------------- decrease the loop area------------normal coaxial cables have parrallel conductors and the loop area is ----- distance--between conductors x length = loop area in a UTP design the loop area is tight ---- closing and opening like----- a bunch of figure eights down the car------ smaller loop area decrease magnetic coupling------------- in normal coaxial cables the coductors are parrallel to any noise on the car body in a UTP design------ the twisting acts to put both conductor in a perpendicular path to the noise------- reducing magnetic coupling to see this simple take a 3" peace of UTP wire lay it on the table in front of you now look at it from the side you see the each loop puts the conductors going to or away from the parallel table suface get it---------- [/QUOTE]
