EMC Antenna & RF Test Accessories


HV TECHNOLOGIES, Inc. is partnered with Schwarzbeck Mess-Elektronik to offer a wide range of high-performance EMC antenna and RF test accessories for EMC applications. We have a huge product selection of EMC antennas from 9 kHz up to 40 GHz and test accessories such as Line Impedance Stabilization Networks and Helmholtz Coils. Schwarzbeck has been in the industry for over 60 years and is known as the worldwide benchmark.

EMC Antenna models for Emissions & Immunity Testing:

  • Horn antennas – 200 MHz to 40 GHz (double-ridged horns, standard gain horns, dual polarized horns)
  • Log-periodic antennas – 30 MHz to 18 GHz (standard LPDA, hybrid LPDA, stacked LPDA, dual polarized LPDA)
  • Biconical antennas – 20 MHz to 18 GHz (balun with removable biconical elements)
  • Dipole antennas – 30 MHz to 3 GHz (telescopic or defined length dipole elements)
  • Loop antennas – 9 kHz to 400 MHz (active loop, Rx-Loop, Tx-Loop, radiating loop, helmholtz coils)
  • Rod antennas – 9 kHz to 300 MHz (vertical active rod, vertical passive rod)

Line Impedance Stabilizing Networks:

Our single-phase and high power 3 phase LISN’s provide a well-defined impedance to the DUT. They supply the necessary mains voltage and current to the DUT and a couple of interferences generated by the DUT to the receiver. They also filter unwanted disturbances coming from the mains supply and protect the mains from unwanted disturbances created by the DUT. Many of these LISN’s are remotely controllable by EMI receivers which helps to automate conducted emissions measurements.


General-purpose broadband pre-amplifiers with high gain and low noise.


Attenuators & Pulse Limiters:

Diode pulse limiters with built-in high power 10 dB or 20 dB attenuator and fuse lamp to protect sensitive measuring equipment. Fuse lamp visually indicates overload conditions quickly and reliably to prevent expensive equipment damage.
