Log-Periodic Directional Antenna with Preamplifier
Key facts
  • Brief description The Log-Periodic Directional Antenna R&S®HL050S7 consists of a Log-Periodic Antenna R&S®HL050 with preamplifier and is suitable for the reception of linearly polarized waves. The integrated preamplifier is extremely broadband and low-noise. It prevents a significant reduction in S/N due to loss in RF cables connecting, for instance, 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. The antenna is preferably used as a feed for the SHF Directional Antenna Systems R&S®AC090 to R&S®AC300.

features & benefits
  • 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 antennaoutput
  • 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
