Radio and TV involve the flow of electricity from a transmitter to an antenna.
The connection between the two (once talking power above 1-kW) is made with hollow (tubing or spiral) in side another copper tubular element. The two kept apart by hard plastic, plastic foam, plastic discs or a plastic spiral.
The "inside" of the tubing isn't needed because it serves no purpose other than to add to expense.
In some installations voids in the separation are filled with rodenticide which suggests it's not a great idea for teething progressives to chew on transmission lines in a vain effort to prevent actual information from being unleashed on the world.
