The antenna has a measured / documented pattern (amplitude and more importantly 
phase). If you have it pointed in a known direction, that information can be used when
post processing carrier phase information. If you are trying to get to mm / picosecond 
levels on an multi hour L1/L2 dataset, that sort of thing can be significant.
