Specifications

Model Frequency range
R&S®HL210A3 1.5 MHz to 30 MHz

Key Facts

1.5 MHz to 30 MHz For high-sensitivity radiomonitoring through reception of ground waves and vertically polarized sky waves

The Log-Periodic HF Antenna R&S®HL210A3 is suitable for the reception of ground waves as well as vertically polarized sky waves and allows even very weak signals to be detected.

According to the physical characteristics of vertically polarized waves, maximum sensitivity is obtained at low and medium elevation angles. The radiation pattern of the R&S®HL210A3 is optimally suited for this purpose. The azimuth range of the R&S®HL210A3 of about 120° can be enhanced up to 360° by adding two further antennas.

For additional reception of horizontally polarized waves and high-angle radiation (predominantly horizontally polarized), the antenna can be combined with the Log-Periodic Antenna R&S®HL410A3.
