Custom design
All MIL types of coaxial cables can be manufactured using the
Flexiform method or process.
Flexiform can be manufactured with a non-magnetic SPC
conductor and with a copper foil under the braid.
Other impedance versions available on request.
Different types of outer jacket are also available.
