I have never put RG 59 in, I haved used it when the only option would be to start tearing things apart. Unless the picture just did not look good, I would try not to put the client through such an expense.

I have only bought or used the RG6 Q4 for new installs. The price has never come up as an option with clients as of yet. Maybe if it did, it would be time to find a new client, you know, since we make so much money on cable:)

Interesting experiment Daniel, was it anything that was noticable in the picture quaility?? Do you have a signal meter, or was it the cable companies, if you do, what do you have.
Some day I need to get one of those things, just not so high on my priority list.
