I answered in the other forum put I'll put it here also in case someone hits this via search. The cable system here (COX) is now up to 1 GHz as of last month. I checked, I think it was the DIY-HD channel the other day and it was at 967 MHz. There are a couple of other channels up there also. That will really test you splitters, coax, etc. I was doing this from memory so thought I better look to make sure: it is actually: Frequency 961.750 MHz
