Both RG-59 and RG-6 come in assorted grades and quality
The difference can be far, far, greater than the difference above.
I do not have the chart on this computer but will try to find it...

That is not the chart I was looking for but it is a start.
It isn't "grades" or "quality" that makes a difference in loss.. It is the MATERIAL that is used for the insulation between the center and the braid/shield (solid insulation has a different propagation speed and can have a higher loss than "foam" insulation).
Solid insulation is OFTEN used in the cheaper "discount" premade cut to length with ends cables, but not ALWAYS..
For that reason I DO mention to CONSULT THE MANUFACTURERS BOOK FOR THE ACTUAL SPECIFICATIONS..
The reason as to why I gave that link is pretty simple..
It ILLUSTRATES very clearly the losses and how much it varies between RG-59, RG-6 for a given length AND FREQUENCY.. And sat receivers make extensive use of 900 mhz - 1.2 ghz areas which is why RG-6 is the recommend cable to use..
Not saying that RG-59 can't be used (it can) but to do so the length MUST be considerably SHORTER than RG-6.
