RG-59 Coaxial Cable Overview:
RG-59/U is a specific type of coaxial cable, often used for low-power video and RF signal connections. The cable has a characteristic impedance of 75 ohms. The 75 ohm impedance matches a dipole antenna in free space. "RG" refers to "Radio Guide," originally a unit indicator for bulk RF cable in the U.S. Military's Joint Electronics Type Designation System. "59" was simply the page of the Radio Guide.
It 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. However, UTP such as CAT6 has too many twists in the twisted pairs, which result as a poor choice of media for analog signals over long distances and thus the preferred medium is fiber optic cable.
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 of its low cost when compared to RG-6. However, given the short lengths provided (usually 4-6 feet / 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.
