Multiple unit antennas, with skew

The number of antennas required to produce a satisfactory horizontal pattern around a relatively large support structure is reduced in a major degree by a new technique known as "skew". Calculated and measured patterns are discussed, comparing normal radially-directed units and those with 90-degree skew. The results with skew angles varying from 90 degrees down to zero are studied. The effects of progressive increase of structure size are shown. Variation with phasing is studied. A mathematical analysis is made for the purpose of disclosing the fundamental basis for pattern improvement by antennas mounted in a skewed relationship.
