Amplifier Research - Broadband Log Periodic Antennas for RFI and EMI Testing
These rugged, dependable high gain log periodic antennas give you the constant high intensity fields you need for RFI and EMI testing in and out of a shielded room. They deliver frequency response and field intensity beyond the norm. AR’s log periodics are designed for high power radiated testing and can be calibrated for emissions.
Their lightweight modular design makes assembly and relocation easy. And they’re built tough, so they can withstand extreme temperatures.
The newest Radiant Arrow®; model ATR26M6G-1, covers 26 MHz to 6 GHz, can handle up to 5,000 W input power, and has extremely low VSWR making it an excellent choice for high field-strength immunity testing. This antenna provides a size reduction of approximately 75% without sacrificing key electrical performance such as gain and beam-width.
From the AR family of bent element antennas comes the Radiant Arrow 80® (ATR80M6G – for fields from 80 MHz to 6.0 GHz) representing a significant advance in the science of log-periodic antennas. The patented Arrow accepts up to 5000 W input, offers 6.0 dBi (± 1.5) gain, and produces a high field even in the toughest applications. The Arrow can also be calibrated for emissions testing. Efficient, compact, and portable, it’s 60% smaller than standard log periodic. For more lower-end frequency responses, AR developed the Radiant Arrow 26® (ATR26M6G), which goes from 26 MHz to 6.0 GHz with at least 10 dB better performance at 26 MHz. The ATR26M250 (for fields from 26 MHz – 250 MHz) is suitable for high-field testing at 15k W.

More Product Information
Over the years, ACS has delivered test equipment and controls projects for commercial aircraft OEMs, tier suppliers, and defense contractors in the aerospace market. We are well-versed in the testing of systems, sub-systems and components used in aerospace development, research, production and Maintenance, Repair and Overhaul (MRO) applications.
AR E-field generators offer exceptional uniformity between the elements. Our ATE10K30M uses low inductance high-power internal load resistors to terminate RF power, and offers well-matched input VSWR. The ATE10K100M is our own patent-pending folded-dipole type design. And we haven’t yet found a test object the ATE10K25M–1 can’t handle.

The FL8000 Series field probes offer a three-in-one solution capable of measuring continuous-wave, pulsed, and modulated electric fields. Covering 5 kHz – 60 GHz, the FL8000 Series works great in commercial, automotive, military, and aviation applications. Each field probe is an electrically small, separable axis sensor capable of measuring both continuous wave and pulsed electric fields offering a unique bandwidth, sensitivity, and dynamic range. Functionality that historically necessitated several types of field probes is now encompassed in a single product.
This series offers exceptional linearity and dynamic range performance to enable the accuracy required for even the most demanding testing. With fiber power connectivity, the FL8000 Series provides an easy migration path, all while delivering the reliability that has made AR the world leader in field monitoring.
