Shop bulk coaxial cable for RF, video, surveillance, test equipment and custom cable assembly applications. Wallco offers RG-style coax, mini-coax and specialty coaxial cable constructions in bulk lengths for field termination and equipment installations.
Compare cable by coaxial type, impedance, conductor and shielding construction, jacket rating, outside diameter and required roll length.
Coaxial cable uses a center conductor surrounded by dielectric insulation, shielding and an outer jacket to carry RF, video and other high-frequency signals. Bulk cable allows installers and equipment builders to cut cable to the required length and terminate connectors for a particular installation.
RG-58 family cable is commonly associated with 50-ohm RF, communications, test and equipment applications. Connector selection should be matched to the actual cable dimensions and construction rather than relying only on the RG designation.
RG-59 family cable is widely used for video, surveillance and other 75-ohm signal applications. Cable construction and shielding can vary by product, so verify the requirements of the equipment and installation.
RG-6 coaxial cable is commonly used for broadband, CATV, video and RF distribution. Standard and higher-shielding constructions may be available depending on the signal environment and installation requirements.
Miniature coaxial constructions are used where multiple video or high-frequency signal channels must fit within limited space. Some specialty cables combine several mini-coax elements with additional conductors for display and equipment applications.
Coaxial cable impedance is an important system specification. Fifty-ohm cable is common in RF and communications applications, while 75-ohm cable is widely used for video and CATV. Cable, connectors and connected equipment should use compatible impedance where required.
Coaxial cables may use braid, foil, braid-plus-foil or multiple shielding layers. Shielding requirements depend on frequency, signal type, installation environment and susceptibility to interference.
Some bulk cable is manufactured with jacket constructions intended for specific installation environments. Where building codes or project specifications require a particular cable rating, verify the exact product listing before installation.
BNC, F-type, TNC, SMA and other coaxial connectors are designed for specific cable dimensions and termination methods. Match the connector to cable type, dielectric diameter, shield construction and outside diameter before assembly.
This category is intended for unterminated bulk coaxial cable and specialty coax constructions. Finished BNC, F-type, RCA and other coaxial patch cables should remain in their appropriate finished-cable categories rather than being grouped with raw cable.
Determine the required impedance, cable family, shielding, jacket rating and total length. Then confirm that the intended connectors and termination tools are compatible with the cable's physical dimensions and construction.
