Spotlight On: Coax Cables RG142, RG174, RG174B/U, and RG179 (Series 1)

Spotlight on RG Coaxial Cables: RG179, RG178B/U, & RG142Our “Spotlight On” series continues to expand; giving you useful information on Allied’s most popular types of wire and cable. Watch our first collection of coaxial cable videos, which highlights RG142 cable, RG174 cable, RG174B/U cable, and RG179 cable. To help you wade through the countless RG cable options, these educational minute-long clips tell you about each product’s materials, ratings, and uses, getting you one step closer to the coax cable that’s right for you.

Like most coaxial cables, these are used primarily for data transmission and radio frequency applications. They can be found in everything from medical equipment to avionic communications systems, and mobile phones.

RG142, RG178B/U, and RG179 cable have temperature ranges of -55°C to 200°C. RG174 has a lower temperature range of -40°C to 80°C. All have different voltage ratings. RG142 cable has the highest at 1900 volts, and RG178B/U cable has the lowest at 1000 volts.

Materials also differ. RG174 cable has a bare copper-clad steel conductor, Polyethylene dielectric, and a PVC jacket while the other three types of coaxial cables have silver-coated copper-clad steel conductors, Polytetrafluoroethylene (PTFE) dielectric, and Fluorinated ethylene propylene (FEP) jackets. Shielding varies. RG142 cable is the only one in this group with a double silver-coated copper braid shield. RG174 cable has a tinned copper braid shield. RG178B/U cable and RG179 cable both have silver-coated copper braid shields.

As you can see, RG178B/U and RG179 coaxial cables have very similar constructions, but different usages and ratings. These can be important factors in choosing the best coax cable for your application. For more information on these coaxial cable options, RG142 cable, and RG174 cable, make sure to visit the
