Abstract: An antenna includes a first radiating array coupled to the mast and a second radiating array coupled to the mast. Each of the first and second radiating arrays comprises a plurality of dipoles associated with a radiation frequency, each dipole coupled to the mast by a standoff. The two arrays are mounted approximately opposite to each other relative to the mast, rather than one array on top of the other array. The antenna may be part of a Positive Train Control (PTC) system and be disposed in proximity to a train track.

Abstract: An antenna element for use in an antenna assembly is provided. The antenna element includes a cylindrical tube. The antenna element also includes a plurality of fingers, each finger having a first end that is connected to the cylindrical tube and a second end that is free. Each finger protrudes inward from a wall of the cylindrical tube. The free end of each finger has an aperture configured to allow the finger to be soldered to a pipe disposed through a generally circular opening. An antenna assembly having at least one antenna element is also provided.
