RG-59RG-59/U is a explicit type of cable, often used for low-power and signal connections. The cable has an impedance of 75, and a capacitance of around 20pF/feet (60pF/m). The 75 ohm impedance matches in free space. RG (for radio guide) was originally a unit pointer for bulk radio frequency (RF) cable in the U.S. military’s. The suffix /U means for general utility use. The number 59 was assigned serially. The RG unit indicator is no longer part of the JETDS system (MIL-STD-196E) and cable sold today under the RG-59 label does not necessarily meet military specifications.

RG-59 is often used at video frequencies. 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, or is used instead. In cases where the transmission distance is too long for these media, such options as UTP or can be used.

RG-59 coaxial cable is usually packed with consumer equipment, such or digital cable/satellite receivers. Manufacturers tend to include only RG-59 cables because it costs less. However, given the short lengths provided (usually 4 to 6 feet or 1.2 to 1.8 meter), this is generally sufficient for its typical use.

RG-59 is commonly used two devices, such optical devices. This is called the higher breakdown voltage of RG-59 allows for higher voltage use in scientific experiments.
