The invention relates to a telecommunications device with an electronic scanning array shaped according to a first surface with rotational symmetry, comprising: a first array of first radiating sources arranged over the said first surface in order to operate about a first central frequency. A coated, oat flake agglomerate is also provided, wherein each agglomerate comprises at least two uncooked oat flakes and has a fat-free coating. The electron accepting moiety is a carboxylic acid, a salt of a carboxylic acid, or has the formula:wherein:X8 is selected from the group consisting of H, CH3, and n6-Z2\u2212, where Z2\u2212 is a monovalent anion; and n6 is an integer from 1 through 10; andQ3 is O or S. The housing and the handle have longitudinal axes that intersect at an acute angle.
