RG-59 is frequently used at baseband video frequencies

RG-59 cable is a precise sort of coaxial cable, frequently used for low-power video and RF signal linked up. The cable has a feature impedance of 75 ohms. The 75 ohm impedance matches a dipole antenna in complimentary space. RG (for Radio Guide) was at initial a component indicator for mass radio frequency (RF) cable in the U.S. military s Joint Electronics Type Designation System. The suffix /U means for general utility use. The number 59 was assigned in sequence. The RG unit pointer is refusal longer part of the JETDS system (MIL-STD-196E) and cable sell today under the RG-59 label do not essentially get together military specifications.

RG-59 is frequently used at baseband video frequencies, such as complex video. It might as well be used for transmit frequencies, but its high-frequency wounded are as well high to allow its employ over extended distances in these applications, RG-6 or RG-11 is used in its place. In cases where the broadcast detachment is in addition long for these media, such options as UTP (unshielded twisted pair) or fiber optic can be used. However, UTP such as CAT6 has excessively many twists in the twisted pairs which results in an inadequately performing media for analog indication over extended distances the chosen medium is fiber optic cable.

RG-59 coaxial cable is usually packed with customer 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 feet / 1.2-1.8 m), this is usually adequate for its typical use.

RG-59 is regularly used to synchronize two digital audio devices, such as ADAT optical devices. This is called word clock.

The higher breakdown voltage of RG-59 allow for higher voltage utilize in technical experiments.


RG-59 cables has a modest fewer signal reduction, or attenuation, over 100 feet. The shielding on RG-59 does not vocation quite as well to uphold Gigahertz level signals within of the middle conductor. RG-6 has an improved design for uphold the signal levels within the core conductor. This is the reason RG6 has turn out to be the usual for broadband CATV and satellite systems. An essential rule of thumb is to use RG6 for any Rapid Frequencies, and use RG59 for video frequencies. RG-6 has an aluminum braid and an aluminum shield. RG-59 comes with a copper braid, and in various instances, an aluminum braid and shield, although this is quite rare.

For any broadband CATV or satellite system, RG-6 is elective by the entire expert. For any signals that are video frequencies RG 59 will be adequate but RG6 might be used as well.
