LOW LOSS CABLE FOR MICROWAVE SERVICE,
Abstract
An investigation was conducted on cellular polyethylene as a further means of reducing the losses in cables at the super high frequencies it showed that the presently commercially available cellular polyethylene compounds are not suitable for such frequencies. The main objection is the increase of the power factor due to the polar residue which results from the blowing agent utilized in such compounds. The effect of moisture on the power factor has proven to be disastrous for the attenuation in the cables. In extruding foam-polyethylene compounds, great care must be utilized in order to maintain consistent expansion to make a cable with uniform capacitance and characteristic impedance. By utilizing a 1/1 weave and smaller size braid wires for the outer conductor, a modified cable was fabricated which is lighter, has superior attenuation stability, and somewhat lower attenuation at 10,000 mc than standard RG-9B/U.
