OK so I am looking to recreate the bad signal pixelated shifting tv image effect seen in bad storms with satellite TV. Just putting an attenuator in between did not work and the attenuators got very hot rather quickly. I later found out this is because the receiver supplies the dish with power. I also have been made familiar with the fact that it is a digital signal and the line between signal and no signal is a very fine line. Does anyone know if there any way to achieve this effect. Someone said there is a way to use an attenuator setup with a shunted ground? I'm a total noob with this but If I can find out how to do it Im sure I can find someone to build a device for me. It was also suggested I put alum foil in front of the dish but that is difficult as the dish is on the roof and its just way too clunky an option.
