The ATH800M6G is a microwave horn antenna that provides high intensity fields that are necessary for RFI/EMI field testing both within and beyond the confines of a shielded room. This antenna is ideal for radar pulse testing in the multiple radar bands over the 0.8-6 GHz range. The ATH800M6G may also be calibrated for RF emission testing. The calibrated model is designated by adding a “CC” suffix to the model number.
