The STLP 9148 is a stacked, logarithmic-periodic microwave broadband antenna with linear polarization. Its laser-cut brass structure and the protective, removable plastic cover make it particularly robust. Thanks to its exceptionally wide frequency range, high gain and very good directivity, it is ideal for EMC measurements, transmit/receive applications and professional test setups in the microwave range.
