Not to be a jackass [Linked Image from sundance-communications.com] RG-58 is very common in CATV (community accesss television)

We use it in our headends to provide reliable connections between video equipment, considering that it inherently uses BNC connectors... which are a little bit more consistant.

You'll find the following cables used in CATV:

RG58,59,59QS,6,6QS,7 (uncommon),and finally 11.

There are few other types that we use for microwave and antenna applications, but mostly we use P type or "hardline" cable for that, which is also what we use for distribution.

Currently, there are a bunch of different hardline varities, mostly we use .500 .540 .560 .750 1" and there are a few others.

The problem with that is that each requires a different type of fitting, and also a different type of coring tool to prepare for use.

All of these cables come in three types:

Filled (which uses a gel silica compound to prevent water from corroding the braided shielding)
House (standard cable used for jumpers, outlets, etc.)
Aerial (filled, and also bound with a steel messenger that's used to support the weight of the cable in an aerial drop situation)

Most CATV companies now use RG-6 exclusively, although RG-6QS is used at times too, especially in high interference areas.

Thomas and Betts has released a snap and seal fitting that does both quadshield and standard RG-6, which is a great bonus for the installer.

Compression fittings, like the Thomas And Betts variety are pretty much the standard these days. Crimp fittings are OK, however, they damage the circular nature to the cable, which can cause bad terminations and faulty reflections.

"Screw on" fittings that you'd find at the hardware store are to be avoided... they produce terrible reflections, and don't pass the shield's connection over to the hardware very well.

The key to a good termination is having the cable stripped to 1/4" of copper exposed, and 1/4" of shield and dielectric exposed. Then, taking the shield and folding it back over the sheath like a bannana, and then slipping the PROPER fitting into place until the dielectric is flush with the back of the fitting's inside. The center conductor should not exceed 3/16" past the end of the fitting.

Hope this helps!
