FOAM HELIAX — A new foam coaxial cable

A new series of foam polyethylene coaxial cables have been developed by Andrew Corporation. They are called FOAM HELIAX and retain the unique corrugated solid copper outer conductor construction so popular in regular air dielectric HELIAX. Two sizes have been developed, nominally 1/2 inch and 7/8 inch diameters, both of 50-ohm impedance. Connectors in type UHF and type N have been developed for these cables and are designed for easy installation with ordinary tools.
