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 periodic antennas 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.
Radiant Arrows, an AR Innovation
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 beamwidth.
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.
