Model	Freuqency range
R&S^®HL410A3	1.5 MHz to 30 MHz

Key facts

1.5 MHz to 30 MHz For radiomonitoring over short, medium and global distances with extremely high sensitivity

The R&S^®HL410A3 is suitable for the reception of horizontally polarized waves and allows even very weak signals to be detected.

The vertical pattern is shaped taking into account the transmission characteristics in the ionosphere. In conjunction with the extremely wide frequency range from 1.5 MHz to 30 MHz, the antenna thus allows reception over short, medium and global distances.

The half-power beamwidth of the horizontal radiation pattern of about 70° can be enhanced up to 360° by adding five further antennas. For the reception of vertically polarized waves, the antenna can be combined with the Log-Periodic HF Antenna R&S^®HL210A3.
