A material handling vehicle guidance system comprises a first conductive member, a second conductive member, and an electrical current source. The second conductive member is electrically coupled to the first conductive member and extends parallel to the first conductive member to define a loop. The first conductive member and second conductive member are coupled to a shielded cable connector. The electrical current source supplies current to the first conductive member in a first direction and supplies current to the second conductive member in a second direction opposite the first direction to produce a narrowcast radio frequency signal detectable between the first conductive member and the second member.
