I am moving my TV from one wall to the opposite---and I need to run the cable wire under an area rug. Amazon has flat cable wire.......How do I know it will work?
They have flat coaxial cable?
Can you provide a link?
I would be suspect it may have issues.
Part of the way a coaxial cable works is because it is round.
If you do decide to try it, make sure you can return with no fees.
This looks interesting if length is OK for you
