Active Receiving Dipole
Key facts
  • 200 MHz to 1000 MHz
  • Optimized for high sensitivity and small size The Active Receiving Dipole R&S®HE202 features a very wide frequency range despite its small dimensions. Its high input sensitivity is the result of optimized matching of the passive antenna structure to the active circuitry. These characteristics allow several passive antennas to be replaced by an Active Receiving Dipole R&S®HE202. Similar to a passive antenna with high-grade preamplifiers, the active antenna is highly insensitive to nonlinear distortion.
