in turn is connected to the output amplifier. The quarter-wave line 

 forms a combining network for the contributions of the various phase 

 shifters. The two groups of eight phase shifters forming one diversity 

 branch are each treated as units so as to facilitate isolating one group 

 in case of trouble or the necessity of reducing the resolution of the 

 antenna system.
