I had a job that I took over after the first installer(an alarm guy) totally f**ked up. They only ran 1 RG-6 to the location of the rear projector, and the customer wanted all the equipment, including HD Sat. in a closet. There was an additional Multimedia run to the central distribution. The home was already compleated, and tearing up the walls was not an option. We would up with on leingh of RG-6 that was about 60 ft. long , and 2 RG-6 that were about 120 ft. long. The picture looked perfect. Since the current is flowing at the speed of light, (186,000 miles /sec.) our unequal lenghs will Not have a visable effect on the picture.
