Rohde & Schwarz HL050S7 Log Periodic Antenna 850 MHz – 26.5 GHz
Description
Rohde & Schwarz HL050S7 Log Periodic Antenna 850 MHz – 26.5 GHz is suitable for the reception of linearly polarized waves.
It consists of the R&S®HL050 log-periodic antenna with a preamplifier. It is ideal as a feed for Antenna systems R&S®AC090 to R&S®AC300.
The extremely broadband and low-noise integrated preamplifier prevents a significant reduction in S/N due to loss in RF cables connecting the antenna to a receiver. Due to its almost rotation-symmetrical radiation pattern, the R&S®HL050S7 offers optimum secondary radiation characteristics for use as a feed in reflector antennas.
Features
- Extremely wide frequency range
- Rotation-symmetrical radiation patterns
- High gain due to V-shaped configuration of antenna elements
- No reduction in S/N due to the use of a low-noise amplifier at the antenna output
- Ideal as a feed for the SHF Directional Antenna Systems R&S®AC090 to R&S®AC300
- Preamplifier can be bypassed via control unit, e.g. at high field strengths
