Abstract
A radio head cable may include an inner conductor and an outer conductor coaxially arranged around the inner conductor. The inner conductor may have a first direct current resistance and a cross-sectional area of at least 5.0 square millimeters. The outer conductor may have a second direct current resistance equal to or less than the first direct current resistance. A first dielectric layer including polyvinylchloride may be positioned between the inner conductor and the outer conductor. A second dielectric layer including polyvinylchloride may be positioned around the outer conductor, and a third dielectric layer including nylon may be positioned around the second dielectric layer.
