Abstract :
Antenna correction factors have been experimentally determined inside a 3 m fully anechoic chamber. In the frequency range of 30-1000 MHz deviations to the manufacturer data, taken from a 10 m OATS, of up to 5 dB have been found in the low frequency range. In the high frequency range the calibration for horizontal polarization was strongly affected, in a narrow frequency band, by the laminated, wooden turntable plate at a 0.8 m height with up to 20 dB
