The Model AT1080 is a wide band, high-gain, log periodic antenna that provides field intensities of up to 500 V/M. With an average gain of 7.5 dB over isotropic and gain flatness of ± 1 dB, the Model AT1080 supplies the constant, high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room. It can also be used as a receiving antenna for RF emissions testing. The Model AT1080 is compact and lightweight for ready mobility, yet is built tough for the extra demands of outdoor use and easily mounts on a flat surface or tripod. Similar to our popular Model AT1000 the Model AT1080 provides the lower frequency response required for many often used test specifications.
