Custom Coaxial and Twinaxial Cables

Uniquely qualified to design your application-specific cables. 

Our understanding of electrical requirements coupled with connector dimensional tolerances allow us to modify existing designs or develop new cables that suit your application while maintaining connector compatibility.

Our experts will help solve your custom coaxial and twinaxial cable needs with high and low temperature extrusion capability and a thorough knowledge of Mil-C-17 and commercial standards make us uniquely qualified to design, develop, and manufacture your application specific coaxial and twinaxial cables. 

With all major UL AWM coaxial component styles, as well as NEC Article 725 and 800 plenum and non-plenum cable approvals, General Wire can provide full regulatory compliance on all of your custom cables. 

Our third party verified performance cable test lab can document and certify all your cable test requirements.  This, combined with our liberal minimum run policy, allow us to provide the cables you want and the quantity you need.


Existing coaxial or twinaxial can be reduced in size while maintaining characteristic impedance and connector compatibility.  Material selection can be utilized to enhance signal loss and cable strength, all while maintaining connector computability.

Low Smoke Zero Halogen (LSZH)

Existing commercial grade or Mil-C-17 type coaxial and twinaxial can be modified utilizing low smoke zero halogen materials while maintaining physical, electrical and dimensional requirements.  We can engineer, design and develop connector compatible low smoke zero halogen coaxial and twinaxial.

Harsh Environment

Expanded temperature range coaxial and twinaxial cables designed to maximize cable life in severe operating conditions.  Existing commercial grade or Mil-C-17 type coax and twinax can be modified utilizing proven harsh environment materials while maintaining physical, electrical, dimensional and connector compatibility requirements.

Secured Communications

Coaxial and twinaxial cables designed to eliminate RF/EMI issues.  Manufactured to DOD/Telcordia standards or your custom requirements.  


Developing and or modifying coaxial and twinaxial cables for medical electronics and sterile environments while maintaining electrical characteristics and connector compatibility.

Composite Coaxial + Twinaxial

Cabling groups of coaxial, twinaxial, twisted pairs or conductors under a common jacket.  Composite cable designs save space and termination costs by allowing you to put multiple components under one jacket.

Full regulatory compliance on all of your custom requirements.

To fulfill our committment to the highest quality standards, we are ISO 9001:2015 certified. We are an approved supplier for the U.S. Department of Defense, and hold all industry standard certifications.
