dc.description.abstract A 34m diameter antenna, built for NASA/JPL in 1990 at Goldstone, California, utilizes a beam-waveguide (BWG) design. It was discovered that if a dichroic plate is installed in a BWG antenna environment, high noise temperatures can result if the receiver system passband is greater than the passband for which the plate was designed. A method is presented for accurately calculating dichroic plate noise temperature for these conditions. en_US
