RG59 Series Digital Coaxial Cable Tri / Quad - Shield 75 Ohm Coaxial Cable
Application:
RG - 59 is often used at baseband video frequencies, such as composite video. It may also be used for broadcast frequencies, but its high - frequency losses are too high to allow its use over long distances; in these applications, RG - 6 or RG - 11 is used instead. In cases where the transmission distance is too long for these media, such options as UTP (unshielded twisted pair) or fiber optic can be used.
RG - 59 coaxial cable is commonly packed with consumer equipment, such as VCRs or digital cable / satellite receivers. Manufacturers tend to include only RG - 59 cables because it costs less than RG - 6 does. However, given the short lengths provided (usually 4 - 6 ft or 1.2 - 1.8 m), this is generally sufficient for its typical use.
RG - 59 is frequently used to synchronize two digital audio devices, such as ADAT optical devices. This is called word clock.
