Here is my tvfool report: http://www.tvfool.com/?option=com_wr...7721121d75e092

I have an XG91 and YA-1713 going into a CM 7777 pre-amp.

There is about 50 feet of RG6 after the pre-amp, and a two way splitter. One path after the splitter feeds a TV through 6 feet of RG6. The other path has about 30 feet of RG6 and feeds a Zenith DTT901 converter box.
