Sounds good, especially the rhombic.  I visited the  VOA (Voice of America) 
receive plant at Furstenfeldbruck (spelling?) Germany in the 60s.  They used 
curtain rhomibics (3 tiers) in a triple space diversity configuration with 
diversity receivers RCA and Racal the audio sounded like it was coming from a 
record.  Then then retransmitted it beaming it to other countries  in
