Is it possible that a faulty AC power source could have an effect on receiving a sattelite signal? I had posted earlier asking what could cause me not to pick up a signal after I had moved a TV system on to my boat in the marina. I have also moved this entire system off of the boat to different sites and have been able to receive at those locations. When I bring it all back to the boat and set it up there is no signal. The only thing that is different is the AC power source. What I have noticed since being in this marina is the GFCI plugs on board will pop frequently. This never happened when we were here before so I was wondering if my no sattlelite signal problem could stem from this. Could a faulty ground/neutral system be the problem.
