Different feed horn configurations with data responses.

2 LNAs orthogonal to one another on the 11" feed horn, with coupler in the foreground.	Cygnus with the 2 LNA feed horn. There are dropouts in the red shift area, and a large drop out at 80Km/sec area, (these should not be there) probably caused by phase interference.
Single LNA short feed horn.	Cygnus with the 1 LNA, short feed horn. Not dropouts, but there are small depressions on each spike.
Long feed horn with 1 LNA.	Cygnus with the 1 LNA long feed horn. Similar response to the short feed horn, except there are peaks on each spike.
