I couldn't find a specific technical answer to this, but anyone out there know what I really need for my runs from a 5-LNB slimline dish? I currently have 4 runs using 2ghz (2250 I think is what sat installers always used in the day). Each run to my multiswitch is about 45 feet or so. It seems that the latest cables used for installs is 3ghz tested, but no D installer has ever suggested changing it. I had a private install of my 5 LNB dish and he suggested the 3ghz would be better. If I do it, I'll end up having it done privately again since D installers don't seem to have white coax and I really don't want 4 50ft runs of black coax down the side of my house.

Is it worth the money to switch from the 2.2ghz to the 3ghz? I'm sure that my inside runs from the multiswitch are the 2.2ghz and I'm not going to change inside wiring.

It is my understanding that your current 2.4 GHz coax is more than sufficient. You shouldn't have to change it. You'll only need the installer to change out your dish and multi switch.

Not worth it really. I believe they are really the same cable just retested to 3 Ghz. I see so many Ka/Ku's with copper clad steel that any solid copper must be good.

I work for Mastec. we use use 3ghz cable. with the new HD channels 2.4ghz will be fine. the signals use from 250 mhz to 2150 mhz to send the data

Solid copper cable is required by DirecTV for all HSP HD installs. The reason for this is not so much signal as power. The voltage from the receiver drops off as the cable length increases, and at some point, it will be too low to switch the multiswitch. Copper-clad-steel cable has more line loss per foot, so you'll run into this problem much sooner than with solid copper cable; thus DirecTV's requirement.

The reality is that most installs can get by with copper-clad cable just fine, because the cable length isn't over 100 feet from receiver to dish. But if you DO have long cable runs, solid copper IS a better solution.

Or use powered switch.

Why, is DirecTV selling them the wire?
