Information about RG Coaxial Style

RG-style Coaxial Cable

Following our popular post about Antenna Coax Cable Types where we talked about the low-loss style coaxial cable used in antennas, we wanted to spend a moment talking about the RG-style coaxial cable.

RG is sometimes attributed to mean "Radio Guide". The different standard RG numbers were originally set by the US government long ago. In fact, the actual letters stood for:

  • R = "Radio Frequency"
  • G = "Government"
  • U = "Universal Specification"
  • A, B, C, etc., = Added after the standard number to indicate a modification from the original standard, such as to change the center conductor from solid to stranded to improve flexibility

So, a cable referred to as RG188A/U is really the universal standard 188, with modification "A", set up by the government for radio frequency use. Today, RG references are no longer precise and are more of a general reference. Individual vendors may have slightly varied specs for the same RG cable, so it is important to understand those specs for your application.

Get the 2013 L-com Master Catalog

2013 Master Catalog is Out!

(blogger@L-com.com) L-com's Newly Released 2013 Master Catalog

Each year L-com produces a Master Catalog, usually with around 260 or so pages of technical information. Yes, it does list hundreds or even thousands of wired and wireless connectivity products, but it is much more than an ordinary catalog as it contains a lot of other helpful things. To start off, the first few pages are a helpful, full-color visual index. Know what you need but not sure what L-com calls it or where they put it? This index helps narrow down where to look! The back of the catalog contains a regular text-based index to get more granular.

L-com's New Ruggedized Ethernet Cabling Line

Ruggedized Ethernet Cabling

(blogger@L-com.com) L-com's new ruggedized Ethernet cables with IP68 connectors

L-com recently introduced a new line of ruggedized Ethernet cables so I thought I would post on some of the features of these cables and why they matter. Ethernet, as you know, has seeped in to nearly every facet of business and life. Now, connectivity is not only essential in homes and offices, but often in industrial sites, large-scale construction sites, harsh environments such as jungles and deserts, and in dangerous or active combat zones. In many cases, cellular connectivity is available, but not all. What happens when you have a location that requires a physical Ethernet structure, but the location itself is damaging or corrosive to that structure?

Panel Mounting Instructions for D-Sub Adapters

How to Panel Mount D-Subminiature Connectors

(blogger@L-com.com) A D-Sub Adapter Bulkhead Mounted

As L-com mentioned in one of its newsletters, D-Subminiature connectors are still used in many applications because of their versatility and lock down mating hardware. Especially in devices that still use serial data to communicate, D-Subminiature is the best solution and so D-Sub adapters are still very popular. One popular application for an adapter is to mount it on a panel creating a port for operators to plug their devices into. Though D-Subs are easy to use, some of the techniques involved in panel mounting the adapters are not intuitive, so this post will go over some tips.
