The Selection of Glide Slope Antenna Patterns for Use in the Frequency Assignment Process

Abstract

The frequency assignment process is meant to preclude harmful interference within service volumes. This is done by choosing frequencies in a manner which provides certain minimum cochannel and adjacent channel desired to undesired signal ratios at critical points of the service volume. One of the factors which affects a station's signal strength in space is its horizontal antenna pattern. Consequently, the horizontal pattern can have a substantial effect on the separation required between glide slope frequency assignments. In some cases, it is desirable to consider the actual antenna patterns involved rather than using worstcase station separations. This report has been assembled so that the directivity of the horizontal pattern may be considered in the assignment process. For each antenna type, a particular antenna pattern is recommended.
