What Does “Coax” Mean?
“Coax” is shorthand for coaxial cable.
What is Coax Cable?
Coax cables send and receive audio/video/data transmissions via electrical signals. They are most commonly used for television and Internet applications within the telecom/datacom industry.
What Does “RG” Stand For?
VESA mount patterns are the series of holes found on the back of a television or monitor, used to attach them to wall mounts. There are a few other names that can apply to these standards as well. VESA stands for Video Electronics Standards Association. The organization VESA is a technical standards association located in California that focuses on computer and video displays. Most major companies that manufacture monitors or televisions (Dell, Sony, Samsung, etc.) are members of the organization and follow its standards. Items made by these members
Different types of cables have different functions and it is easy to view any cable as a single, working unit. But each cable is made of different layers, with each layer providing a different function. Learning how these pieces interact makes it easier to understand just how a cable works and what can be done to avoid damaging a cable.
Coax is one of the most common types of cable, having been in use for well over 100 years. While the technology has improved over time, the basic layout
Cables to Keep Around the House
Spring is here and a lot of us are going to use that nicer weather to get a little cleaning done. If your house is anything like everyone else's, there is probably a junk drawer somewhere with a big mess of old cables. After untangling all the knots, you will want to look at each cable to see what you should keep and what can be tossed.

Coax cables are capable of transmitting radio frequency (RF) signals and have served as the backbone of communications technology for decades. From radios to telephones to televisions to computers, coax cable has seen continued use even as the technology it supports continues to evolve. Stretching back over 100 years, the origins of coax cables begin towards the end of the 19th century.

Coax cables are fairly simple to assemble, but there are a few different ways to go about doing so. Having a good coax signal is heavily dependant on installing a connector correctly. If you are unsure about how to install a coax connector, see our installation guide here.
Whether crimp, solder, compression, and twist-on is the best option will depend on the exact setting the cable will be used in. Consider questions such as:
- Is the cable low- or high-voltage?
- Will it be used for field-work or factory-work?
- How experienced are the individuals working with the cable?
- How long is the cable expected to last?
- What is the budget?
- Will the cable be in a hazardous environment (extreme temperatures,
Cable switches are used to connect multiple signal inputs (computers, DVD players, video game consoles, etc.) to a single output (televisions, computer monitors, etc.). Switches all work on the same general principle and most are purely mechanical. A switch only goes from multiple inputs to one output; if you need to go from one input to multiple outputs, you will need a splitter instead.
Switches are used when you have a screen, such as a TV or computer monitor, that does not have enough ports. For example, say you have a TV with one HDMI port but you want to connect a DVD player, a laptop, and a video game console. One option would be to constantly reach behind the TV and switch the cables, but that gets old fast. The simpler solution would be using
Cable splitters are used to connect multiple TVs, computer monitors, or other devices to a single signal source. There are differences between the various types of splitters, but a few general rules apply to them all. Splitters only go from one input to multiple outputs; if you need to go from multiple inputs to one output, you need a switch instead.
When a signal goes through a splitter, it is divided and becomes weaker. Imagine an HDMI splitter as an example. Modern HDMI cables are capable of a 4k signal, which works fine if you are using a single HDMI cable by itself. However, say you use a 4-way HDMI splitter to run four cables to four TVs. Each signal would only have half the normal strength so none of the TVs will have 4k quality.
Because the signal is evenly divided, the signal will become weaker for bigger splitters.
Coax is one of the oldest types of cables and has withstood the test of time, still being used over 100 years after its invention. While many stores today have pre-made coax cables available, sometimes another option is needed. Users may need a cable in an unusual size or just need to replace a broken connector. This guide will show users how to put coax connectors onto the end of bare coax cable.
