[amsat-bb] Lindenblad or DCA???

[Hans (BX2ABT)]

Hello all,

Been reading up on satellite antennas and something is not clear to me: 
are the Lindenblad and Double Cross Antenna (DCA) one and the same 
beast, or not? They look the same and the only difference I can find is 
that the Lindenblad seems to be slanted 30 degrees towards the horizon 
and the DCA 60 degrees.

Any old timer here who can enlighten me on this?
