Receiver chain:

On the ground

• gnd 1   looking down the horn axis towards horn
• xband is on axis , sband is  off axis
  
• gnd 2   side view of receiver chains
• sband chain (off axis)
  
• sband polarizer
• elbows to take 2 pols off axis
• directional couplers for cals
• waveguide amps then  output cable
• xband chain (on axis)
• polarizerj
• elbow to take out the second pol
• waveguide couplers for cal injection
• waveguide amps then output cable
  
• gnd 3   side view or receiver chain
