The outer braiding of coaxial cable is a electromagnetic shield to protect against interference.
It is earthy, it balances the line, protects the inner core (signal wire) from outside interference and protects surrounding equipment from interference too.
A coax cable has a center conductor surrounded by an insulator and then a metal braid. You are likely referring to the braid.
To extend a coax cable without special tools you will need a second coax cable. You can plug the second coax cable into the end of the first one (the end that is plugged into the wall).
Cable modems use RG-6 coax cables.
coax.
Air core coaxial cable has the dielectric insulation between the braid and center conductor supported by a partially hollow plastic spacer. By replacing any solid plastic with air or partially air the losses are reduced and velocity of propagation is increased.
This would depend upon your TV and the receiver and if it has a coax port available on the back. You can use an RG6 coax cable between the receiver and TV. Most newer HD receivers do not have a coax port on the back
The best size is RG 6 coax. However for short runs RG 59 will work.
For Dish Network, we use RG6 coax cable to allow a higher frequency range for the satellite signal from the dish to your receiver. Any coax cable not rated at RG6 could affect the signal.
It's the coax cable used for Thick Ethernet.
Typical coax cable uses a different standard than RCA. You will need to use a converter box.

UTP & COAX cable's are used
