Rohde & Schwarz HL024S9 Log Periodic Antenna 1 GHz – 18 GHz
Description
Rohde & Schwarz HL024S9 Crossed Log Periodic Antenna 1 GHz – 18 GHz is suitable for the reception of linearly and circularly polarized waves.
It consists of the R&S®HL024A1 crossed log-periodic antenna and two broadband preamplifiers. The antenna can also be used as a feed for the R&S®AC008 microwave directional antenna.
Due to the integrated switching network, horizontal, vertical, left-hand or right-hand circular polarization can be selected. The preamplifiers prevent a significant reduction in S/N due to loss in RF cables connecting the antenna to a receiver.
Features
- Wide frequency range
- Broadband preamplifiers
- Switching network for horizontal, vertical and circular polarization
- No reduction in S/N due to the use of a low-noise amplifier at the antenna output
- Can be used as a feed for the SHF Directional Antenna Systems R&S®AC090 to R&S®AC300
