RG 58 Coaxial Cable

  • RG-58 is suited for low power signal connections, and can be purchased in 50 or 52 Ω impedance.
  • Used in a laboratory for testing, the RG-58 cable usually passes signals through the BNC connector.
  • You may have noticed that most two-way radio communication systems, such as marine, CB radio, amateur and police use a 50 Ω cable to work properly.


RF coaxial cable is easy to install, very durable, and inexpensive


RF coaxial cable offers good resistance to electromagnetic interference


RF coaxial cable also perform very well over short distances such as home installations


About RG 58 Coaxial Cable

Cloom is proud to offer a broad assortment of RG58 coaxial cables in various lengths, ranging from 3 feet all the way up to 1000. Our BNC RG58/AU Coaxial Cables come in black and feature copper-nickel for maximum conductivity with no interference or distortion. Our expansive selection of wires also includes large reels, which is perfect for Ethernet coax systems. This option features a bare copper center conductor and can be spooled up to 1,000 feet per reel. For those looking for bulk orders, we also provide 95% braided Ethernet coax systems without connectors so that it’s easy to connect any system economically. Cloom has the perfect solution for your CCTV setups or video installations! With our premade coax cables of all lengths, we can provide your home or business with just what you need.
