Condition is: I have a TV satellite Dish antenna and its LNB needs power which come from TV setup box through coax. The LNB of dish antenna takes power from the coax and sends UHF singals through the same coax. I am going to use two setup box in two rooms. Two watch TV, I need to power LNB from both setup box, so LNB gets power from box A or B (both became 'master'.
In this condition, I am planning to put diodes in series so power from one box do not kick back to another. And to pass UHF signal from LNB to the boxes, I an thinking to use 1nF capacitor parallel with these series diodes. Does this work?
