The DF-A0273 is a single band, compact 4-Channel DF antenna intended for direction-finding from 20 to 500 MHz. The antenna uses crossed-loop array principles that provides maximum possible sensitivity for its compact form factor. The loop designs incorporate patent pending technology to mitigate cross-pol disturbance.The antenna presents patterns suitable for 4-channel correlative DF (CIDF).The DF-A0273 has low noise amplification on each channel with passive bypass capability, an integrated noise source for calibration and an electronic compass
