A few things.
RG-213 is single shield RG-8 coax so that would not be good.
Keep in mind that Times is selling coax.
It is not as much the shielding but the fact that the shield and the foil move
and cause noise in your system. It has been talked about time and time again
here on RP.
Good luck,
Yes it will but you will have to touch up the receiver.
