I'm still confused (note that we do not have Dish Network in Europe) but you question seems to be about "increase from volts, amps and resistance" which are not directly related to any TV distribution system. As I understand it, the cable to the dish itself carries power to the LNB (down-converter) and the power comes from the receiver box along another cable. The DP34 is a combiner, passing power from one or more receivers to one or more dishes, it passes the power through in one direction and the signals in the other. The resistance is a property of the cable itself and shouldn't change at all, except for a tiny shift with temperature, almost unmeasurable. When you say the volts and amps increase, how are you measuring those and what exactly are the volts and amps you see?
