Need some advice

Pardon me if this has been asked (many times before) but...

I am a complete rookie when it comes to HDTV. I have been with DirecTV for years. I recently stepped into the world of HD, new HD plasma TV, DVD w/upconvert, HR20-700S, etc.

The interconnect wiring between the components I understand. Its from the dish to the receivers that is my issue. I have scheduled a new dish install for HD (5LNB), but they keep mentioning RG6 cable. My house is wired with RG59 (I believe). I have 2 DirecTV Sat/DVR receievers in 2 rooms with a third room running off a wireless transmitter from one the others. I plan on putting the HD system in the room with wireless and keeping the other 2 as is. There is no way to bring a new line to it without punching a new hole from the outside and then some serious snake work is needed.

Do I really need RG6 or will RG59 suffice?
Can I multiswitch the signal to 2 rooms via 1 cable or are two cables (either RG6 or RG59)?

Thanks for any help.

They are both 75 Ohm coaxial cables but the RG-59 is smaller and has a lot more losses especially at higher frequencies. You would be much better off using RG-6. In fact the installer may not be willing to use your existing RG-59.

I'm not sure about the multiswitch, I have no experience with those.

Before my upgrade, used existing cable system rg59, probably because I didnt know any better and the installer was allowed to take a shortcut. Watched the training videos for installs of new 5lnb and mpeg4 systems and they stressed that rg-6 be used. Installer of my upgrade also insisted on using new rg-6 run and shook his head when he saw what was in place. I would say do it correctly now, any problems down the road and you will be second guessing if the wire is to blame. Like drinking bourbon from a paper cup vs. the bottle. Maybe you notice a difference, maybe you dont, or maybe it eats a hole through the bottom! cd:2cents

A friend (an R&D electrician from my company who understands satellite installs) will be coming over to help me run all new RG6 cables throughout. He said the same thing... It might work, it might not, but how many times do you want to fix the same problem? This way its done right and I don't have to pay the contractor for fishing cables. Lastly, its done the way I want it.
