[amsat-bb] Lindenblad or DCA???

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?
