The preamplifier of the active dipole has very high linearity (input IP2 = 70dBm, input IP3 = 31dBm) and low noise temperature (100-360 K). The frequency dependence of the dipole impedance and the match between the dipole and preamplifier have been optimized to achieve Galactic noise limited operation. The ratio between the antenna temperature due to Galactic noise and the noise temperature of the preamplifier is 10 ± 1.5dB over the whole 10 to 70MHz range. The total cost of the active cross-dipole is 220 euro.
