  Results will be shown from the ASTRONEU array developed and operated in the
outskirts of Patras, Greece. An array of 9 scintillator detectors and 3
antennas were deployed to study Extensive Air Showers (EAS) as a tool for
calibrating an underwater neutrino telescope, possible other applications in
muon tomography, education purposes, and last but not least, the detection of
air showers via their electromagnetic signature. This is the first stage of a
total of 24 scintillator counters and 6 RF antennas to complete the array. In
this work, results with regard to the electromagnetic detection of showers will
be shown. The method of operation and analysis will be presented. The purpose
of this project was to demonstrate the adequacy of the method to detect cosmic
events even in the presence of high urban electromagnetic background, using
noise filters, timing, signal polarization, and eventual comparison with well
understood event reconstruction using the scintillator detectors. The results
indicate that cosmic showers were detected and the method can be used for the
complete array.
