There are quad shielded cables that have an extra layer of foil and braid shielding and can offer better protection. Military s joint electronics. Plenum and nonplenum cable part numbers 22 145 02 22 145 03 22 146 02 22 146 03. Rg59 coax cable has an interior constructed of a bare copper clad steel wiring for a conductor and polyethylene dielectrics.

Rg for radio guide was originally a unit indicator for bulk radio frequency rf cable in the u s. Note that attenuation values are given at 400 mhz but can and do often have significantly different values at other frequencies. The cable has a characteristic impedance of 75 ohms and a capacitance of around 20pf ft 60pf m. However newer coaxial cables can use a 95 braid to perform better without the extra bulk and weight of quad shielded cables.

Rg 59 u is a specific type of coaxial cable often used for low power video and rf signal connections. With its single shield this cable will have a high resistance against signal loss and keep the interior safe.
