OPTIMIZED BANDS

Scalar horn feeds result in excellent antenna performance and are the standard choice for communications bandwidth applications. Low cross-polarization, excellent impedance match, wide bandwidth and close pattern symmetry are characteristics of all Seavey Engineering scalar horn feeds. All feeds are supplied with mounting provisions and are fully sealed with aperture windows for use in outdoor environments.
