Alpha Essentials Coaxial & Micro Coaxial Cable:

For a complete range of 50, 75, 93, and 100 ohm coaxial, twinaxial, and triaxial cables, we offer a wide range of insulation and jacket materials meeting the requirements of military specifications and regulatory agencies such as UL and CSA.  For broadcast quality video transmission, our precision video cables use FEP dielectrics to achieve low capacitance, high velocities of propagation, and tight tolerances for maximum signal integrity.

Try our newest addition to the Alpha Essentials Coaxial Cable line, Micro Coaxial Cable!

Micro Coax is ideal for customers looking for signal transmission options, especially when designs offer limited space for cable routing. Micro Coax is offered in a full range of standard sizes from 50 to 32 AWG using high-strength silver-plated or tinned-copper alloys rated up to +200°C and is in-stock in 100 meter put-ups available for immediate shipping.  Alpha Wire now offers Coaxial cable products ranging from 10 to 50 AWG.
