USLP 9142 Schwarzbeck Log Periodic Antenna

Introduction：

The USLP 9142 is a log-periodic antenna from Schwarzbeck MESS, Germany. The antenna's antenna coefficient stays in the range of 23-39 dB/m over the full operating frequency range, and you may need to add a preamplifier to increase the signal-to-noise ratio in actual testing. Suitable for both UHF and SHF bands, the antenna maintains linear polarization over the 650MHz-8000MHz range, and can be used in EMC laboratories for RF field strength emission and RF radiation reception testing of the object under test in a wave darkroom. The antenna is authorized to be sold and serviced by EUTTEST in China, please contact our sales for quotation information.

UHF and VHF bands What are they?

The Chinese name, English name, and frequency range of UHF and VHF are shown below, respectively:

Very High Frequency (VHF) : 30MHz-300MHz

Ultra High Frequency (UHF) : 300MHz-3GHz

UHF and VHF can transmit both analog and digital information in practical use.

For a definition of the radio frequency bands available globally and a description of their utilization, please refer to: Radio Magnetic Spectrum Division Frequencies and Utilization .
