I currently have Cox Digital cable which is pretty good. The problem is I have been told that in my area they currently have no interest in going HDTV. I have contacted a dealer about DirectTV and had thought I had a pretty good deal. Three receivers (Hughes) with one of them being DD capable at no cost for the reciever upgrade and $50.00 to upgrade to a 3LNB dish for future HDTV upgrade (can't swing the HDTV receiver cost at this time). This would put the total cost at $50.00. The problem is he said that he will use the existing RG59 cable and a Diplexer instead of running RG6. The runs I currently have that he will use are all less than 75 feet each at the most (probably more like 30 feet each on 2 and maybe 50 feet on the third). I am going to keeb basic cable for local channels. Do you think this work?
