Rent the EFG-3B E-Field (billboard, hoarding, & bowtie array) antenna for up to 2kW of power over 10kHz to 220 MHz frequency range. It is made to generate electric field intensities within limits for radiated susceptibility testing systems. This test equipment is ideal for easy integration with Teseq, EM Test, and Milmega setups. It is effective given the design as a radiating transmission line. This equipment can be rented in with an amplifier or individually to supplement testing capabilities.

Horn Antenna 300 Watts CW

Double Ridge Horn Antenna Features: 

      • 700MHz-18GHz 300 Watt Continuous Limit 
      • Linearly Polarized High Gain, Low VSWR
      • Individually Calibrated & Rugged Construction
      • FCC, MIL-STD, VDE and TEMPEST Testing
      • Turnkey Solution - Arrives Ready for Testing!


The SAS-571 Double Ridge Guide Horn Antenna made by A.H. Systems is a lightweight, compact and has been manufactured for maximum gain, low VSWR and broadband response. Using broadband double ridge guide horn antenna  antennas is the ideal for many EMC testing standards and is the antenna of choice per Mil-Std 461G over 200 MHz. This A.H. System horn antenna is an excellent solution for both immunity and emissions testing with adjustable elevation and azimuth.

The double ridge guide horn antenna was initially designed for surveillance where a high gain broadband response was required. The original design was to have a 30-degree beamwidth, which is ideal for EMI measurements and compliance testing. The SAS-571 horn antenna comes with a 3" mounting bracket and thumbscrew allowing for attachment to the tripod. This antenna has the ability to meet a large range of EMC testing capabilities with additional accessories available.

      • One 1000 A (50/60 Hz) Inductive coil
      • Current Transformer Mounted Direct on Inductive Coil
      • Turnkey Solution - Arrives Ready for Testing!


High power low frequency magnetic fields (16 2/3 , 50, 60 Hz) are measured near mains power, railways, trams, trolley-buses, low voltage heating oven, welding machines, induction ovens and busbars for energy distribution networks. Generally monitors, microphones and hall sensors are sensitive to magnetic fields. The IEC standard 61000-4-8 defines the 50/60Hz magnetic field test, the IEC 61000-4-9 the SURGE magnetic field test and IEC 61000-4-10 the damped oscillatory magnetic field test.
