Abstract: A sectionalized electromagnetic antenna formed of a plurality of co-linear stacked dipole sections. Each of the sections includes a plurality of co-linear conductor elements for conducting an electrical current. A phasing section is disposed between the conductor elements to shift the phase of current through the adjacent conductor element. A connector fitting is located at each end of each of the sections for detachably mechanically and electrically connecting one of the sections to another of the sections. Sections may be added or removed from an antenna of the present invention to obtain a desired gain, radiation pattern or overall length.

Abstract: Disclosed is an apparatus forming at least a portion of an antenna and the method of constructing the same. A generally cylindrical casing is formed to hold a spacer having a generally cylindrical outer surface. The spacer has a generally axial aperture extending therethrough to receive an antenna transmission line so that the line will be spaced from the outer surface of the spacer and the casing. An antenna wire is braided around the outer surface of the spacer to locate the same between the spacer and the casing.

Abstract: Disclosed is a unitary bracket for holding down an antenna mounted on a vehicle. The bracket includes an elongate body portion having one end configured to be readily clipped onto the gutter strip of the vehicle. The other end of the body portion is configured to receive and hold the antenna in a position generally paralleling the roof line of the vehicle. Because different styles of vehicles have different sized gutter strips, the end of the body portion which is clipped onto the strip can be made universally adaptable to the various sized strips.
