Coaxial Cable Diameter

Properties of standard coaxial type cables have been very much standardized for many years.

Coaxial cable diameter.

These are extremely thick cables which are much more industrial than any of the other varieties and are expensive to boot. Pasternack s coaxial cable impedance calculator allows you to enter the outer diameter dielectric width inner conductor diameter width and either the dielectric constant or velocity of propagation vop values in order to calculate the impedance of the coax. Often used for the transmission of radio frequency signals rg316 cable can also be used in wireless communication broadcast and military equipment. For heavy duty signal transmissions a variety of popular brands are available.

Hardline cables typically measure up to or more than 1 2 inch thick. Coax type characteristic impedance outside diameter velocity factor atten 100 mhz atten 1000 mhz comments. When more common dielectrics are considered the best loss impedance drops down to a value between 52 64 ω. Its size makes it look very different to other types of cable such as twisted pair or ethernet cable.

If you need to run cable in excess of 150 feet your installer may recommend either an lmr 600 or a half inch coaxial cable. Hard line coaxial cable hardline cables are often used for high signal strength applications as with radio transmitters or other devices. But the differences between the two cables do have a large impact on the cable s performance. The most commons sizes of coaxial cable are rg 6 rg 11 and rg 59 some of the size differences are demonstrated in the image below.

What is rg316 cable. Unless you buy rogue stock from a supplier if you abide by the manufacturer s application guidelines there should not be any surprises. The inner components are generally made of the same material as the the rg 6. For a coaxial cable with air dielectric and a shield of a given inner diameter the attenuation is minimized by choosing the diameter of the inner conductor to give a characteristic impedance of 76 7 ω.

The insulation diameter is 7 24 mm and the outside diameter is 10 3 mm. It is easily identifiable as it is a very thick cable and hard to work with. The cable diameter of the rg6q cable is also slightly larger than the rg6 cable.
