I have a possible application of needing to feed a video projector with an analog video signal. I would use a VGA cable except the cost and effort of installation are rather huge. I already have the module to convert VGA to analog composite video, I am wondering about how well it would work with a length of about 150 feet to the projector. Both the source and the projector ports are 75 ohms, as is the RG-6 cable, but I am concerned about losses and the frequency response, and the effect on the video. Does anybody have any experience in this area??
