The DRH18-E from RF Spin is a wide band, high gain, microwave horn antenna that operates from 1 GHz to 18 GHz. It provides a gain of 6 dBi. This Dual Ridge Horn Antenna has been specially developed for EMC/EMI Applications based on 13 years of experience from the older model. The model DRH18-E is lightweight and compact, yet can cater to the extra demands of outdoor use and easily mounts on a tripod. The antenna supplies the constant high intensity fields necessary for RFI/EMI field testing and is also designed to perform emission measurements when calibrated. The DRH18-E is supplied with VSWR, Gain and Antenna Factor calibration data at 3 meters.
