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
Europe/Africa
