Where can I return with G-11 coax cable?

I want to connect a TV in my detached garage which is 150 foot from my cable entry box connections. I would like to use a heavier gage cable to fetch the signal better rather than a booster. I'm told the gage rating is G-11 but I can't find it. Please comfort.

Answers: Almost Any satelite instalation company or supplier will have the cable you are looking for.
