  One successful detection technique for high-energy cosmic rays is based on
the radio signal emitted by the charged particles in an air shower. The LOPES
experiment at Karlsruhe Institute of Technology, Germany, has made major
contributions to the evolution of this technique. LOPES was reconfigured
several times to improve and further develop the radio detection technique. In
the latest setup LOPES consisted of 10 tripole antennas. With this, LOPES 3D
was the first cosmic ray experiment measuring all three vectorial field
components at once and thereby gaining the full information about the electric
field vector. We present an analysis based on the data taken with special focus
on the benefits of a direct measurement of the vertical polarization component.
We demonstrate that by measuring all polarization components the detection and
reconstruction efficiency is increased and noisy single channel data can be
reconstructed by utilising the information from the other two channels of one
antenna station.
