Someone on another forum who had the same problem wrote 4 years ago:
"Hi,
I'm not the original poster, but I had the same problem as did / do quite many here in Finland. Karuselli located the problem and it only happens when computer is not connected to earthed wall socket. You have to install galvanic isolator between your DVB-card and antenna socket. Signal line can be connected directly but ground has to be galvanically separated. You can place 1nF condensator between technisat antenna socket ground and antenna cord ground. You can also buy these galvanic isolators to antenna socket from special shops. They can not be found from every market.
I don't know but I quess this only happens with this new 1.0A version of Technisat cards. I've had no problems at all after I made this galvanic isolator."
Can anyone help me doing this? If I don't misunderstand I have to buy a capacitor of 1nF and put it between my antenna's ground and the skystar's ground. Is it right?
I have a question on it. If I connect only the antenna's core cable to skystar (only for some seconds so that not cause any hazard, without the grounding) shall I have signal quality? |
