    Patent number: 9293804
    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.
