The Rohde & Schwarz HL050 is a log-periodic directional antenna engineered for radiomonitoring, measurement, and EMC testing across an ultra-wide frequency band. Its V-shaped element configuration delivers rotation-symmetrical radiation patterns and linear polarization, making it equally effective as a standalone receiver or as a feed element for reflector and microwave directional antennas. The HL050 combines broad frequency coverage with mechanical durability and integrated amplification options, supporting both passive and active measurement scenarios from site surveys to precision signal analysis.
