What is RG in coaxial cable?

When referring to different types of coaxial cables, RG stands for “Radio Guide,” a designation derived from World War II military specifications. Each type of coaxial cable has a different RG rating to help distinguish the cables’ distinct characteristics and specifications.

What is the difference between RG8 and RG213?

RG-8/U is the same diameter as RG-213 (. 405″), while 8x is much smaller (. 242″). RG-8/U is also much closer to 213 in terms of loss, while 8x suffers almost twice the loss per 100 feet.

What is 93 ohm coax used for?

93 ohms was once used for short runs such as the connection between computers and their monitors because of low capacitance per foot which would reduce the loading on circuits and allow longer cable runs.

Are RG59 and RG6 connectors the same?

The main difference between RG6 and RG59 is that the RG6 cables have a thicker copper wire allowing better transmission of the signal. RG6 is primarily being used today for satellite and digital cable TV, where higher frequencies are required that RG59 cable cannot support.

How thick is RG213 coax?

10.00 mm thick
The RG213 /U is a 10.00 mm thick radio frequency cable suitable for most RF applications.

Is RG213 better than RG8X?

It depends on the frequency you use the coax on. RG-8 is fine for HF 1-54 MHz, but once you get above that then the loss is higher. At 100 MHz RG-8 loses about 4.8dB. RG-213 has a huge loss of 7.2 dB at 400 MHz & above at 100 feet.

Which RG rating of coax is used for cable modems?

RG6 is typically a double shielded coaxial cable about 6.86mm in diameter with a center conductor a bit larger than that of the RG59 type. RG6 is commonly used in Cable TV, Satellite TV and Cable Modem applications due to its low attenuation over high frequencies.

Is LMR 400 the same as CNT 400?

CommScope CNT-400 is their Ultra Low Loss Equivalent of Times Microwaves LMR-400. Famous for years as a manufacturer of high quality Coaxial Cable, Commscope now offers this option for quality cable installations.

What is better than LMR 400 coax?

RG-8, RG 213, RG 214 coaxial cables are the same physical size as LMR-400 – yet their attenuation is up to 40% higher and they have significantly inferior RF shielding performance. The aluminium foil outer conductor gives unsurpassed shielding of >90dB versus >60dB for RG-8, RG 213 and RG 214.
