RG59 armoured coaxial cable serves indoor shipboard video and signal-distribution circuits specified for 75 ohm connections. A solid bare copper centre conductor is insulated with foam PE. Aluminium/polyester/aluminium tape and tinned copper braid form the screening system, followed by LSZH bedding, tinned copper braid armour and an LSZH outer sheath. Match the cable to the signal format and equipment requirements before selecting the route length.

20 AWG solid bare copper conductor with a nominal diameter of 0.8 mm.
75±5 ohm impedance and frequency-specific attenuation data.
Two screening layers, separate braid armour and a nominal overall diameter of 10.0 mm.
Use 75 ohm connectors whose dimensions suit this armoured construction. Compare the operating-frequency loss with the equipment budget, allowing for patch leads and connections. For digital video, confirm the signal format, equipment limits and installation length; a generic RG59 designation does not specify every video interface.
RG6 Armoured Coaxial Cable, 75 Ohm, Dual Screen and LSZH Sheath
RG11 Armoured Coaxial Cable, 75 Ohm, LSZH Marine Signal Cable
Is this a 50 ohm or 75 ohm cable?
It is a 75 ohm construction, with a listed tolerance of ±5 ohms.
Which layers provide the screening?
An aluminium/polyester/aluminium tape screen and a tinned copper braid surround the foam PE dielectric.
What is the nominal cable diameter?
The dimension table lists a nominal overall diameter of 10.0 mm.
Can a video transmission distance be selected from the RG59 name alone?
Use the actual signal format, operating-frequency loss and equipment limits to determine the permissible route length.
What should be specified at the cable entry?
Confirm the finished diameter, connector geometry, screen and armour termination, sealing requirement and the listed minimum bend radius of 15 times overall diameter.
