The term coaxial refers to the inner conductor and ...
If a coil is made using coaxial cable near to the feed point of a balanced antenna, then the RF current that flows on the outer surface of the coaxial cable can be attenuated. One way of doing this would be to pass the cable through a ferrite toroid. The end result is exactly the same as a 1:1 current balun (or Guanella-type balun).

Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. This contrasts with broadcast television, in which the television signal is transmitted over-the-air by radio waves and received ...
Cable television first became available in the United States in 1948. [ 1] By 1989, 53 million U.S. households received cable television subscriptions, [ 2] with 60 percent of all U.S. households doing so in 1992.
