To electriczipper,

If you have a very long run of coax, Rg-11 will offer less line loss than RG-6 because the the center conductor is a larger diameter wire.

The second thing to look at is the coax grade, outdoor is meant to be placed in the elements or buried in the ground, and indoor grade, has to be run indoors. Then I have heard some mumbling about quad shielded but I understand little of that. And I have also head that black is the best color for outdoor grade coax. The other thing I have head is the coax line losses increase with the frequency of the signal, so if you have many high UHF stations its far more import than if you have mainly VHF.

In terms of my real world practical experience, the antenna hooked up to my house when I bought it was wired with decidedly inferior Rg-59. When I made my upgrades for digital, my set up became 35' of hard to retrofit with RG-6, RG-59, that gets into my basement, then to a splitter, one side of the splitter feeds one TV connected with 50' of indoor Rg-6, the other side of the splitter feeds my other TV that is connected by 75' of RG-59. Until I added a distribution amp ahead of the splitter, the TV fed with RG-6 got 2 channels more than the TV fed by RG-59. And the distribution amp not only gained 2 more channels, it also equalized reception for both TV's. I could easily replace my indoor RG-59, but why bother?
