Log-periodic directional antenna consisting of R&S®HL024A1, two broadband preamplifiers and a switching network for linear or circular polarization

The directional R&S®HL024S9 consists of the Crossed Log-Periodic Antenna R&S®HL024A1 and two broadband preamplifiers. It is suitable for the reception of linearly and circularly polarized waves.


Due to the integrated switching network, horizontal, vertical or left-hand and right-hand circular polarization can be selected.


The preamplifiers prevent a significant reduction in S/N due to loss in RF cables connecting, for instance, the antenna to a receiver.


The antenna can also be used as a feed for the SHF Directional Antenna Systems R&S®AC090 to R&S®AC300.
