Plus you can't easily run them inside of walls and underneath flooring. Plus if you are going to use coax, you'd probably want RG6 or else the inner wire will be way too thin.
I can see that being the case, since a linear amplifier will amplify ambient noise in the line, however, if you're making long runs, especially in parallel to AC power lines, I can see coax as a huge benefit versus straight braided wire.
The other arguments in regard to flooring/angling are moot since you run coax for CATV/SAT.
Not trying to be dominating; I was hoping to find out why I was wrong, and I respect your input.
