COAX wiring your office or home.
Coax cable is used to transmit radio frequencies (RF) for internet connections, TV signals, and antennas over a copper network. It is still the most common wiring in your house or business for TV. RG59, the smaller, is still used for CCTV (closed circuit TV). RG59 has been replaced by RG6 & RG11 for TV because of its poor shielding and higher signal loss over distance compared to RG6 and RG11.
