For runs of more than 100 feet, there are in-line signal boosters you can obtain to keep the signal up and hopefully reduce signal loss/interferance. I feed up to 100 feet of S-video signal into a DA, then up to another 100 feet into the receivers – projector, screens, recorders, etc.
Beyond that, I would be likely to use in-line signal boosters/amplifiers between the DA and receivers. MarkerTek, B&H Photo Video and many others sell these items.
