Twisted pairs support less bandwidth than coaxial cable or optical fiber. Twisted pair cables are available unshielded (UTP) or shielded (STP), with UTP being the most common. Shielded twisted ...

You either need amplifiers along the path, or need to use expensive, high quality shielded co-ax cables ... signal is then fed into the twisted pair cable through impedance matching resistors.
