The Rohde & Schwarz HL023A1 is a log-periodic dipole array antenna engineered for electromagnetic compatibility testing, field monitoring, and broadband signal measurement across the VHF through microwave spectrum. This antenna delivers virtually frequency-independent radiation patterns that ensure uniform illumination of the device under test, making it ideal for emissions and immunity characterization, signal polarization determination, and direction-of-arrival analysis.
