LOPES30 is a digital radio antenna array working in the frequency range 40 -- 80 MHz with 30 dipole antennas triggered by the air shower experiment KASCADE-Grande. From an absolute calibration the measured field strength of the LOPES30 antenna system is known and the invesitigation of a large data set taken in east-west polarisation is performed. The reconstructed pulse height of the radio emission in extensive air showers is the measured quantity to be compared with the KASCADE-Grande reconstruction parameters, like primary energy or shower geometrie on a single air hower basis. The resulting correlations will also be compared with expectations from detailed Monte Carlo simulations.
