Is my dish and wiring HD ready?

A year or two ago I switched from Dish network to Direct TV because of a greater channel selection. At the time I was told to purchase the "new" oval style, triple LNB dish because that would be HD compatible. I did not purchase an HD ready receiver. The local installers (highway robbers) put the new DTV dish on the same post mount used previously for the round Dish Network dish, and then connected it to the same two coax cables used for the Dish Network system that were installed over six years ago. A freind that recently had Direct TV installed has 3 cables, all of a larger guage coming off his Triple LNB dish. Question is, will the two cables I now have be adequate for HD reception? or will I have to replace the whole thing?

If the cables were working for a SD Directv receiver, they will be fine for the HD receiver.

Thanks for the response. I'm just wondering why some new installations I've seen use three cables from the dish? Is there a good reason to have three?

Most likely they are feeding three receivers.

If I understand this correctly then, if you only have a single LNB homerun cable, you can run one box, but that's it?

My existing wiring only has a single LNB running to my unit, and I'm trying to figure out if I can run a single HD box with that. I know it'll also harm DVR possibilities, but I don't have many choices, and I'm trying to decide about upgrading.

If you want HD service from D you need the Phase III dish. There are ways of doing it with muliple dishes and multi switches. Buy you really don't want to go there. :D

I understand that...but my point is that I only have a single LNB home run cable. *If* I can run HD by just getting a new dish and using the existing wiring, I'm prone to try it.

So, again...if I have a new dish, can I run just one cable to one box and use HD? Or is there something about the HD signal that *requires* multiple cables (like seeing many satellites or something)?

If you have the oval dish then you would only need one cable for HD. If you purchase the HD Tivo system then you may want to think about running a second cable. This would allow you to record one show and watch another.
